Migrating to new servers

SUGGESTED

Client uses Sage 300 2014 & SQL 2012, on separate servers.  They have provided 2 new 2019 servers for us to begin the upgrade -- but first, I want to make sure that everything works as it does now, before installing version 2022.  The DBA restored the SQL databases to the new SQL server, but I am unable to do DBSetup in Sage 2014.  The DSN got created, and it tests successfully in ODBC setup, but DBsetup gives me a connection error 49153.  Ideas?  I realize we're combining old and new technology here, but I'm not sure exactly where the problem is.  Thanks in advance for any help.
