Upgrade Methods 1 Server Pros Cons Same Server Multiple Instance Migration Pros No second server needed Cons Need increased drive space Need to change apps to point to an instance name instead of default Likely to not meet SQL 2016 criteria with current OS / requirements The same methods as 2 servers can be used

Upgrade Methods Upgrade Methods 2 Servers Pros Potential hardware upgrade at the same time Recovery is much easier 2 Server Upgrade Methods DB mirroring Log shipping Backup restore Detach/attach

Migration of Encrypted Items Upgrade Methods Migration of Encrypted Items 2 Servers Script and migrate logins Migrate job/tasks Replication SSIS Migrate encrypted items Move a TDE protected database to another SQL Server

Post Migration Requirements DB properties including trustworthy Orphan users DB ownership Rebuild indexes/update statistics Rename server
