Upgrade from ITMS 7.1 SP2 MP1 to 7.5

Hello,

We have been asked to perform and document the analysis / considerations / best practices for upgrading our current ITMS 7.1 SP2 MP1 environment to 7.5.

It would be of great help if people around could help / share their experiences about the upgrade, issues identified, any precautions they may have taken, things to be considered, etc.

Thanks
