Sitecore Azure: Moving an Editing Farm from One Geographical Region to Another

The Background

NOW Digital deals with many clients whose websites are in the cloud, and many of these are using the Microsoft Azure cloud platform. Sitecore works relatively seamlessly with the cloud and is intrinsically well suited to perform on the Azure platform. To assist with this, Sitecore have provided the Sitecore Azure module, which plugs into Sitecore and connects you to the cloud, allowing you to perform deployment operations via a local on-premises (deployment) environment.

Now, the cloud might be akin to this godlike entity that never fails in most people’s minds, but in practice it still suffers some of the same limitations as regular hosting environments. It also still has the concept of “servers” existing in a particular location, even though it tries to abstract this and call them something else.


  • “Cloud services” are similar to web servers, and these exist in a region.
  • “SQL Azure” databases exist on a server, which exists in a region.

As such, you also get latency. If you, for example, are located in Australia and the “environment” (whatever it is) is located in the US, then you get latency because of the time it takes the data to travel that far.

For our purposes, the latency difference between Southeast Asia and Australia East (regions that are in relatively close proximity) was significant enough (approx. 1-2 seconds per page load in a delivery environment) that the client wanted to shift their environment from Southeast Asia to Australia East in order to service their primary market (which is Australia), but retain a delivery environment in Southeast Asia to service the Asian market.

Now, Sitecore’s Azure implementation allows three primary configuration options:

  • Live Server – Editing & Delivery both hosted on the one server.
  • On-Premises Editing – a CM/CD setup, but with Editing in a local (on-premises) environment and Delivery in the cloud (you can have as many Delivery Farms as you like)
  • Editing in Azure – a CM/CD setup but with Editing in the cloud as well (i.e. you have one Editing Farm in Azure as well as your Delivery Farms)

Our client had the latter of these three, and in particular, they wanted to move Editing, because it was considerably slower than it should have been based on Sitecore’s typical performance output, and the responsibility for this lay with latency.

Only One Editing Farm

Sitecore’s Azure module allows you to relatively easily add new Delivery Farms with the click of a button in the Sitecore Azure module. It also, however, allows you to customise what it’s doing by manually editing the nodes that are created in the Sitecore content tree under the system -> modules -> Azure section.

(This becomes important later, so write that down.)

In fact, to “shift” a regular Delivery Farm the process is relatively straightforward:

  • Create a new Delivery Farm in the desired region.
  • Publish all content to this environment.
  • Change the IP / Traffic Manager configuration.
  • Decommission the old Delivery Farm.

Theoretically, I thought to myself, what I could do is proceed down the same path, except with an Editing Farm.

Unfortunately, Sitecore’s Azure module:

  • Doesn’t provide a way to “Move” an Editing Farm.
  • Rather studiously enforces the whole “only one Editing Farm allowed” rule.

This rules out the possibility of using Sitecore Azure to create a new Editing Farm for me.

Or does it?

Surely somebody has done this before, we thought. It must be online somewhere. Sitecore must have documentation around it.

So we researched it. And researched it. And researched it.

Time came for us to move the Editing environment and, despite a wealth of information now available online about how to use Sitecore with Azure, the pros and cons and how to do this and that, there was absolutely zero information on how to move an Editing Farm from one region to another. Clearly it wasn’t a common requirement.

So we contacted Sitecore’s support portal and got nothing (though, in fairness, they did eventually come back with a solution slightly different to the one shown here, and one earmarked with the caveat “this isn’t thoroughly tested so be careful”).

What Help Is There?

During this research, I did come across three relatively useful articles on how to “customise” your Azure configuration, one each in regard to cloud services, databases, database services and storage services.

These provided a handy insight as to “how the Sitecore Azure module” actually works behind the scenes. For those who have used it, you will realise that its black box nature can be somewhat frustrating when trying to do something new and relatively undocumented / untested.

These four articles are:

The important thing about these articles was that they implied that, if Sitecore Azure can find something, it uses it, and if it can’t find something, it creates it.

This theory also seemed to be confirmed by my own testing when I had been mucking around with creating new Delivery Farms over time.

Another useful link is “how to clean up after a failed Azure deployment”, which gives you good insight into what artefacts Sitecore Azure creates and how you can manually manipulate them:

As such, these articles all implied the Sitecore Azure module was relatively robust and I “should” be able to wrangle it to work in my favour by potentially fooling it that an Editing environment didn’t already exist.

This one line (above) is effectively what this solution is all about.

The Setup

In any case, it’s important to note that this particular process worked well for us given our current environment. It might not necessarily work well in other environments depending on the configuration.

So take note of this setup:

  • Sitecore 7.1 (rev 130926) with Sitecore Azure 3.1
  • Azure with Editing in the Cloud
  • SQL Azure / PaaS model
  • Editing Farm in Southeast Asia
  • Delivery Farm in Southeast Asia
  • Delivery Farm in Australia East
  • Analytics, Core & WFM shared between all environments, and residing on a server in Australia
  • Each Delivery environment has its own “web” DB
  • Editing also has a “web” DB (for previewing published content)
  • Traffic Manager in place handling delivery

Note that we are wanting to shift Editing from Southeast Asia to Australia East. Note that there is already a Delivery Farm in Australia East, meaning that a “storage” blob already exists in that region.

So: if your configuration sounds similar to this, press on.

Be Careful

First and foremost, before doing this, you should be very careful to:

  • Inform your content editors about a content freeze during which time they won’t be able to update the website
  • Backup all your databases (including delivery, just in case

Getting Ready

  1. Create a blank cloud service in the new region using your desired name. Remember to use the correct naming convention or you could blow up Sitecore Azure. Specifically, this means using “Ae” instead of “Sa” in a name such as “clientabcprodsace01role01scddc”.
  2. Initiate a content freeze.
  3. Backup all databases using Export feature in Azure portal. Specifically export “master” and (editing) “web” databases to a storage blog container in Azure, as these will be the ones shifted to the new region. Also backed up core, analytics and WFM, as well as all delivery databases, just in case.
  4. Create a new DB server in the new region. Set the password to some randomly generated password that is 12 characters long in keeping with other SQL Azure passwords (
  5. Create a new database in the Azure portal using the “restore” option. Select your backup from your storage blob container, and do this for “master” and “web”.Ensure the name of the restored database is in keeping with Sitecore Azure standards (e.g. if you’re shifting from Southeast Asia to Australia East, you should change “SaCe01” to “AeCe01”, in the name of the database.Also remove the timestamp off the end of the name of the database so it will have a “nice” Azure DB name that is in line with all your other databases.
  6. Once complete, login to your on-premises deployment server using RDP, the one you use Sitecore Azure on to manage your deployments.

    This server is the one where you go to run the “Upgrade Files” command
  7. In the Sitecore Content Editor on this environment, expand system -> modules -> Azure -> [YourEnvironment].
  8. Expand the region your editing environment is currently in (e.g. Southeast Asia).
  9. Drag-and-drop the “Editing01” node into the region you want it to be in. Note all this does is tell Sitecore Azure to “draw” the dot for the editing environment in the new region. It doesn’t actually change any underlying structures in Azure.

Now you’re going to “fool” the Azure module by manually updating the configuration, bearing in mind you’ve already:

  • Created a new cloud service that is empty
  • Created a new database server
  • Restored master and web onto this server.

Fooling Sitecore


  1. Update Storages -> Default item fields to match the storage fields already included in the equivalent Delivery01 storage node. In other words, you’re going to use the same storage service as the Delivery01 environment already uses. These fields are:“Service Name” – set to the same name as the storage already associated with that region (grab from the Delivery Storage node)“Primary Access Key” – set to the same as the storage already assocaited with that region (grab from the Delivery Storage node)

    Based on my testing, if you didn’t already have a delivery environment here (and thus no storage service), you could theoretically set these fields to blank and it will create it for you, but I haven’t tested this behaviour.

  2. On the Sql01 node, set the name of the server you created.“Server Name” – set to the name of the DB server created in step 4 (Getting Ready)
  3. Expand the Set01 node, and for each (“master” / “web”) database node, update the connection strings for the target database.“Target Database” – set the full connection string for the new database on the new server you restored in step 5(Getting Ready)
  4. On the Production node, update fields as follows:“Service Configuration” – update the settings below so that the connection strings (which are for storage services) have updated endpoint names and account keys matching the storage service details you set in step 1 above (Fooling Sitecore)These two connection strings are in the XML, and are called:


    DNS Host Name” – set to be the name of the empty cloud service you created in step 1 (Getting Ready)

    Connection Strings” – update the master and web connection strings to include new server / catalog name / password combination (if you use this particular field to override connection strings)

    Private ID” – set to blank (this maps to the “deployment ID” of the deployment once created, and since it doesn’t exist yet (cloud service is empty) we want Sitecore to create it for us

  5. Now, open up the “ConnectionStrings.config” file on this on-premises deployment server and add the new connection strings (for master and web) to this file as well (remove the old ones if you want).IMPORTANT: Connection string names should be in the format: [CloudServiceName]master_[ServerName] (substitute “master” for “web” when doing the other database).


At this point we’ve created our empty cloud service,

told the content authors not to update anything, moved our master & web databases, and we’ve setup a manual configuration in Sitecore to try to fool the Azure module into believing the Editing environment still needs to be created.

From here:

  1. Restart your application (on-premises deployment server) by modifying the web.config file.
  2. Open the Sitecore Azure module (not the Content Editor this time).
  3. Select “Production [Production]”.
  4. Your editing instance should now be visible in the new region you dragged it to, and it will no longer detect the old Editing environment you’d previously connected.As such, it will show a Blue Dot say “Resume Deployment” when you click on it.
  5. Select “Resume Deployment”.
  6. Select your machine instance size (Extra Large or A4 recommended).
  7. You will be prompted because all databases are already in existence. Select “OK” to use all existing databases as-is.This will not make any changes to the existing databases and simply connect in place. Do this for master, web, analytics, WFM, core and any other database you’ve shifted.
  8. Deployment will take place. This may take some time (up to 30 mins to 1 hr depending on connection speed, etc.)You can keep a tabs on it by viewing Sitecore log files, which are updated when Sitecore does something and also the Azure portal itself, which will periodically update.Your cloud service in Azure will eventually have a single instance created in it within the Production slot. This will be where your files will be uploaded and where your Editing environment will soon live.
  9. Once deployed, you may need to ensure that your publishing targets and connection strings are correct on the Editing environment.Since you backed up and restored master DB, publishing targets will still be
    visible in Sitecore as they were previously
    , but the file “publishTargets.config” is generated by Sitecore Azure during deployment and this tells those publishing targets their database details. For some reason this file seems to only use the publishing targets of the current region’s delivery
    and ignores all others.So, if your setup is like ours, the Southeast Asia delivery publishing target was omitted. We had to manually add this, which is not ideal give any custom changes are deleted each time an Azure instance is re-imaged (which happens monthly or whenever Azure performs an update).

    We are currently investigating a more permanent resolution to this last issue and will update this post when it is found.

  10. Likewise, repeat this process for ConnectionStrings.config. See above notes around the persistence of this update.
