As far as you move all the data inside it for Exchange it will be ok if you delete it. The good thing is that if there is anything remaining on it exchange will not allow you to delete it.

There is not any kind of issue from the Exchange perspective on deleting the default database.

However, (and there things are not very common...) there are some special cases where you require access because of third party configurations. For example, if you are using specific antivirus exclusions on your database and log files directions, you should update these exclusions in the antivirus. If you are executing scripts that somehow are pointing to that database name it is also something to update. In the same way if you are using monitoring or backup software that makes any reference to these databases, you might update these products as well to include the new changes. And finally, you can schedule to restart your MSExchangeIS service after adding or removing databases in order that Exchange distributes better the RAM memory across the database instances that are running (but usually there is no urgency with this).

I ran that command for I new there where some system mailboxes.  It's in queue.  I guess once those and the other mailboxes are moved I can purge it.  Do I need to set one of the new DBs as the default now?

Hi Gopher,
Once you moved arbitration mailboxes you can delete your mailbox database.
FYI you wont be able to delete your mailboxdatabase if it contains mailbox.
These 3 command will show you if it has mailboxes/archives
Get-Mailbox -Database <old database name> -Arbitration
Get-Mailbox -Database <old database name>
Get-Mailbox -Database <old database name> -Archive
