Exchange mailbox migration - Should I move the following mailboxes?

We are in the process of upgrading from Exchange 2007 to 2013, and I've moved all of the user mailboxes. The following mailboxes remain on the 2007 server and I wanted to check whether I should move these as well.

1.      Launch IIS Process Account (IWAM_DNSXNY1@x.com)
2.      Internet Guest Account (IWAM_XNYEXCHG@x.com)
3.      Internet Guest Account (IWAM_XNYEXCH@x.com)
4.      Evault Mapi (mapi@x.com)
5.      CAS_{bfe46a446c9b42d4}@x.com)

Thanks.

Hmm. These aren't Exchange System Mailboxes. I would say move them. Or, disable them and see who screams.

Do you have any archiving solution like Enterprise Vault, as Evault seems to be related to Enterprise vault. I suggest for which application you are using these mailboxes, as moving them to new server might break them. In these case you need to find the owner for each mailbox and then plan to move it.

The first three all seem IIS related. Seems like someone gave a mailbox to the Internet Guest account. Probably not needed. But err on the side of caution.

I guess the catch-22 Is that eventually I will be shutting down the old Exchange server, so these mailboxes may just go with it - at which time I may find out that I need them. However, moving them now may break something, hence the inquiry.

These mailboxes are all probably not even needed, as I don't believe we have an active Enterprise Vault solution, and the IIS accounts probably didn't need a mailbox.

EVault may have also be the EVault cloud backup service.

You will need to remove or move them though. Otherwise you wont be able to remove the old databases.

My suggestion is if you don't know who is using them app or user then just move them to a group/database you know you can delete in a future.

If something is going to break, better have the mailbox with any that might be inside than nothing and start from scratch.

Also, as stated by Gareth you still need a decision or you can't remove the old 2007.
