As support (and running on old hardware) is fading out for SBS 2003, we are considering upgrading to essentials R2, as suggested by microsoft. The exchange environment will be migrated to Office365, but what about SQL server. It is used in our backend and a lot of Stored procedures along with self developed code is running (and needed). I don't see anything mentioned about SQL server in the migration documentation. Can it be done, and what about the licenses (we use it in a commercial environment)?
A full SQL server would cost around $3.000, which is not acceptable in our budget.
We run the SQL version included in the SBS 2003 Premium version, and only use the 'SQL Server Agent' for scheduled maintenance plans and some cleanup jobs.
