V5R1 and SP15.1

Hi List,
We are planning on upgrading our OS/400 from V4R5 to V5R1 very soon. My current OW XE is on SP 15.1.
Do I need upgrade my OW SP 15.1 to the latest SP before I upgrade my OS/400 or can I stay with SP15.1?
Did anybody upgrade the OS to V5R1 in the past and the OW SP is on 15.1?

We are on V5R1 and SP 15.1 with no problems.

There is one issue that stands out in my mind. There are problems saving changed processing options in the design tool. This has been corrected in SP 18.1.

We just did our upgrade past weekend but I had problem with the Client Access ODBC driver and the CWBODBC.DLL is at version 8.0.4.4.
We just received the newer version from IBM which is at version 8.0.4.6 and it lookslike fixed all the problem we encountered.
