Upgrading BW 7.3 to 7.4, what are changes to be done in BPC 10.0 SP11

Hello All,

             I am working on BPC 10.0 SP11 on BW 7.3 and we want to upgrade the BW 7.3 to BW 7.4.

So are there any changes required to be done on the BPC side or is it just "backup and restore" or any other method to do the same.

Thank you.
