Hi Sandra,

1. Can I upgrade the RCVCAT schema in the 11g database so it will support my
12c database?
Yes. The RMAN compatibility matrix is explained in MOS note #73431.1. The
catalog database has to be 10.2.0.3 or newer.

2. If yes, will that affect the backups for the 9i, 10g, 11g databases?
Yes, probably bugs etc.. However you should have 2 catalog databases/schemas -
one for test and one for production and so you can test it.

2. If yes, is there any impact/gotchas having a 12c catalog in an 11g
database?
Yes, please check this blog post:

We recently created our first 12c database. Our backup scripts expect the
database to registered in the catalog. Unfortunately, the catalog is in
an 11g database which isn't scheduled to be upgraded until 2nd quarter of
2016.

Questions:
1. Can I upgrade the RCVCAT schema in the 11g database so it will support
my 12c database?
2. If yes,
o will that affect the backups for the 9i, 10g, 11g databases?
o is there any impact/gotchas having a 12c catalog in an 11g
database?
Thank you in advance.
