We have been asked to migrate to SQL Server 2017 from 2012. Only coding experience as background we are not so aware of what are the crucial points to consider or to worry when migration.
Some of the points I'm concerned are:
Is there is anything missing in 2017 which was working fine in 2012. Missing in the sense of an upgrade in 2017.
Can we restore a backup from 2012 in 2017
Also is there is any chance of any kind of data truncation or something like that if we restore DB backup from 2017 into 2012 (If restoration possible)
