Hello - I am in the middle of a migration from SBS2011 to Exchange 2016 using your guide. I am at Step 11 - Move User Mailboxes to Exchange 2016. The default location for the Exch 2016 mailbox is on C. I need to move this to another drive before moving mailboxes because I will run out of room on the C drive. Any problem doing this at this point? Do I just change the mailbox database path in the database settings? Thanks!
Yes, that can be done. I would stop migration batches from the EAC and then start moving files. The guide for this is here How to move Exchange Server 2016 or 2013 mailbox database and logs to another drive. In addition I would turn of circular logging until the migration is done, read How to enable or disable circular logging and why and when you should do this
