I've done a bit of searching trying to find an up-to-date solution to this but I'm not so certain with Google support answers nor with previous threads here.
We have multiple domains on a Google Apps for Business account and we want to move most of them ( not the primary one ) to their own separate Google Apps accounts (so they will be the primary domain respectively for each new account).
What is the best option to do that without data loss?
The entry for data migration in Google supports omits any mention to domain transfer and where that would take place in the process.
The most comprehensive answer I found is from 2012 and I'm not sure if it still applies.
