Pro-active validation/verification of two applications merge

If you have an application A running Oracle database into which you are going to merge another application B running Oracle as well, how would you proceed, proactively, to have an idea of whether application A is going to merge the volume and activity of B without any problem?

The two applications can be on the same Oracle version as well as on two different versions.

I am thinking of the following criteria

· CPU time

· DB time

· IOPS · Transactions/Redo

Thanks
