Revert ODS51 to ODS48

I can not open a NSF File ODS51 (Domino R8.5) in my Domino Server (R8). Error message is ‘Invalid NSF Version’. I have tried to compact -R, but it’s still show me ‘Invalid NSF Version’.

Anyone know how to revert ODS51 (R8.5) to ODS48 (R8)?

Subject: Compact

Did you try running the compact on the R8 server or R8.5. This would only work on the 8.5 server and you may need to set Create_R85_Databases=0

Any joy ?

I tried to run on R8.5 after read your message and success revert to ODS 48.

Many thanks. :slight_smile:
