Issues in migrating the users

SaravanaKumar_bq49sy

We are planning to migrate the data from the confluence server to the confluence cloud. Our users have different usernames in the cloud and server because of the company merge.

So we are planning to migrate only the spaces, not the users. And we are having our old username and email(username and mail id configured in the server) in the cloud as inactive users.

If we migrate only the spaces, does it creates any conflict?
On migrating just the spaces, do it correctly identifies the users in the deactivated state and match with them or what happens in that case?

I might not have the best answer to you but I will share my experience.

When I migrated from server to cloud, we had also different usernames in server and cloud because two different companies joined and we had two different Active Directories. The thing to note here is that user merge in migration is done by email address not the username itself. 

I chose to migrate only users that were related to projects/spaces that I was migrating. 

Some users had accounts in cloud already and some users were created during migration but they didn't have access to any data. I migrated them only to see the history because if you don't migrate users to Cloud, it shows "deleted user" as an actor, but I didn't want that.

But if you already have them in Cloud as deactivated but same email address as server, it should match. 

I had some disabled accounts in both instances and they did merge correctly.
