This is the second part of the Exchange 2013 to Exchange 2016 migration. The first part can be found here:
Now that we have 2 functional Exchange servers, it's time to migrate the data.
Migration of public folders
The first step is to migrate the public folders. In contrast to Exchange 2010 and earlier, the public folder migration from Exchange 2013 to Exchange 2016 is child's play. If you do not use public folders, you can skip this part and continue directly with the migration of the mailboxes.
There is a mailbox for public folders on the Exchange 2013 server
This mailbox contains a few public folders:
To migrate the public folders, only the mailbox for the public folders needs to be moved to the Exchange 2016 database. This can be done quickly using the Exchange Management Shell:
Get-Mailbox -PublicFolder | New-MoveRequest -TargetDatabase DB2016
The status can also be queried using the shell:
Get-MoveRequest
Depending on the size of the public folders, this can of course take some time. The following command can be used to check in which database the mailboxes for public folders are stored:
Get-Mailbox -PublicFolder | ft name,alias,servername,database
That was all. No more setting up folder replication, just move public folder mailbox. Wonderful.
Migration of mailboxes
Before the mailboxes are moved, the offline address book must be assigned to the Exchange 2016 database:
For the sake of simplicity, I take all mailboxes with me in one go, including system mailboxes. Here, however, everyone can decide for themselves at which points in time which users are moved.
The next step is to assign a name and specify the target database:
In the last dialog, you can control when the switch to the new database should take place, either directly after the move or at a selectable time:
The migration batch has been created, so wait until the move is complete:
At some point it will be done
By the way: Does anyone remember this message? A thing of the past, no restart necessary.
In the third and final part, the environment is cleaned up and Exchange 2013 is uninstalled. Coming soon.
