I have a client who has stood their ground with SBS 2011 until now and needs to be migrated from 1 single server running SBS2011 to two server 2019 servers, one running Exchange. There are only 10 users
The catch - the existing SBS2011 server is being repurposed as the 2nd Server 2019 server running Exchange 2019.
I am considering two methods
- Build the 1st 2019 server and join to the SBS domain to receive the AD, export the mailboxes from the existing 2010 Exchange, wipe the SBS server and install server 2019 + exchange 2019, import emails....
- Build a new domain altogether on the new server, export the mailboxes from the existing 2010 Exchange, wipe the SBS server and install server 2019 + exchange 2019, import emails....
- has anyone planned and executed either of these migration scenarios and can provide some tips?
- After joining the 1st 2019 Server to the SBS2011 domain, it will inherit the Exchange 2010 schema that exists in the AD. Will this introduce issues to the new Exchange Server?
- I have always favoured a new domain to get rid of corruptions, legacy AD content added by past applications (especially sites that dont have UPS's to protect the server aganst sudden loss of power resulting in Ad corruption). Is my bias to this wrong?
- Do you have good case that would sway me to one method?
