Dear,

A customer has to support your post on my server. They are 150 accounts .

As recommended migration?

I understand that these steps would be :

1. Create the accounts on the new server .
2. Configure DNS , with both MX . Priority 10 for the old server to the new priority 0 .
3. Migrate , account to account . Each bill, Migrated , delete from the old server .

Until that is completed with the migration , users on the new server would use only the webmail.

Any recommendation? Or good practices ?

Thanks for All!

Sorry for my English!
