What's wrong?

 

Resolution:

Once you upgrade the product from the lower to the higher release and you take with you the history files of the lower release and start writing to them in the higher release, you can't use them if you fallback to the lower level again.

If you try to use them again with the lower level Datacollector, you'll get the following error:

DBG21023E TEST 16:07:47 HISTORY: FILE HSTSTATS INVALID HISTORY FILE. 

DBG36017E TEST 16:07:47 OPEN FAILED FOR DDNAME HSTSTATS 

 

The best option will be to create a new R18 files if you want to fall back.
