What's the proper procedure for back-revving some patches for OES2?

I had received some FTF patches from Novell for NetStorage issues related to DFS junctures back in November.

The patches fixed the problem.

Unfortunately I stupidly updated my OES2 system with the patches from the channel and it seems the FTF patches never made it into what got released into the channel, so the channel overwrote the ones I had.

Do I just reinstall the "old" FTF ones again via the rpm commands?

Or do I have to remove the .15 versions of the NetStorage patches first and then install the .14 FTF versions I have?

I'd report this via an SR but the customer center has been down all day (in the meantime I've emailed the tech directly to let him know the newer patches don't have the fix in them).
