Migration from Higher to Lower Version of DeltaV

I have some configuration (Composites Library) with Standard DeltaV function blocks in DeltaV 11.3 and DeltaV 12.3.

Can I migrate these so I can import them into an older version of DeltaV 10.3

(So the other way that the migration tool works).

Can this be done (and tried) by changing text at the top of the fhx file before importing?

    There is no supported migration utility or process to downgrade to lower revisions of DeltaV.

    You could possibly replace the header and it would work but I know that v12 has new items in the FHX that will cause an import to fail. You would then have to manually remove all of these references that get documented in the Import log from the FHX to get it to import successfully. I think that v11 also had some new items added in the FHX as well.

    If you are only do a few composites it wouldn't be that hard to do this to find and remove these.

    Good luck.

    In reply to Matt Stoner:

    Matt is correct. There are new features and fixes from one releases to the next. To that point, the older releases might and probably will have issue with the new codes and might even corrupt your database. Is it a risk you want to take. If you do, make sure you have a backup of your database before you proceed. Good Luck

    Depending on how many and how complex the composites are it would be wiser to re-build them in v10.3. If there expressions in the composites, these can be copied straight from the FHX file. (After it's done you could upgrade and compare it with the original v11&12 exports to make sure everything is the same.)
    If you have a lot of objects, the suggested 'stripped' import could work. Beware of possible embedded blocks in the composites.
