Should I upgrade to icloud drive after installation?

[iMore Question]

My iPhone 5s got locked and I had to do a recovery. After that I backed up my data from iCloud. No it is asking me if I want to upgrade to iCloud drive. If I do this would it cause any further problem?

It's your choose but is not required

You can go back into Settings later on and enable iCloud Drive at any time
