Best Practices

- Don't attempt upgrade if there are already obvious issues with your current environment. The current issues might create larger problems if you attempt to upgrade. Fix all problems first.

- If you fail an upgrade attempt , do not continue to attempt upgrade on same database. Fix the upgrade problems , then attempt upgrade on the database on which you have never attempted an upgrade yet.

- As a pre-requisites make sure you backed up all your data including database , document library and image gallery.
