A lot has been written about how to migrate from Single Tenancy to Multi-Tenancy. Video’s have been created, blogs have been written, Sessions have been given.. . The question that I always get – is “what about the other way around?”. So, how do I migrate back to a Single Tenant Environment?

I’ve spend some time to sort this out for you. And it wasn’t that difficult. In fact, it’s easy and logical. Just one trick to realize: when you export an app, it’s not only possible to export it to a new database, but it’s also possible to “export” it to an existing database.

So basically, migrating a Tenant to a Single Tenant database, means:

  1. Dismounting the Tenant
  2. “Export” the app to that Tenant database
  3. Start a server in Single Tenancy mode to that database

Or .. when you want to move a complete Multi Tenant environment to a Single Tenancy Environment, it’s quite the same:

  1. Move all companies (or the ones you want to convert to a single tenancy database) from all tenants to one (new) tenant
  2. Do the exact same as above with this tenant

As I said, the real trick is the export of the application to the tenant that you want to migrate.. . I wrote a script for that:


This script is creating a function that needs two parameters: the SourceServerInstance and the SourceTenantID. And then, it will create a Single Tenant Database of that tenant. You can use this “function” in a script like this:


The script above is going to convert a tenant to a Single Tenancy database, and going to set up a new (Single Tenant) ServerInstance for that database.. .
