When you create a database for example with the extenson .ns7 the ODS will be ODS43 instead of ODS51.
This kind of trick was used in earlier days and was to ensure that an older ODS was used when really needed.
What this causes is that the DB class of the database instance is set to that version.
And you cannot use a copy style compact to change this database to the new ODS -- even you rename the extension back to ".nsf".
The only way to change the database class and ODS was to create a new replica.
In Domino 9 there is a new compact switch "-upgrade".
"-upgrade Upgrade databases created with older DB classes to the most recent class."
This switch upgrades the DB class to a general DB (DBCLASS_NOTEFILE)
#define DBCLASS_NOTEFILE 0xff01
#define DBCLASS_V6NOTEFILE 0xff10
#define DBCLASS_V8NOTEFILE 0xff11
#define DBCLASS_V85NOTEFILE 0xff12
Some C-API based applications have created databases with specific DB classes and run into the same issue.
With this new compact switch you can change the ODS for those databases quite easy.
This even works when you don't change the extension of the file. But for best practices you should rename the file anyway.
So a compact -C -upgrade help/ will upgrade all your help databases to the new ODS.
Some of the help databases have an old DB classe and a normal compact will not bring them to the new ODS.
you can verify this via the "show dir" command:
sh dir help

This can be quite helpful. I know that also an anti-virus vendor hat issues with databases created with the wrong DB class.
