Can I find out the disk format version in any way, e.g. with python-lmdb?
The id2v DB only exists in OpenLDAP 2.5 databases. However, stay tuned...
Ah, this is very helpful:
mdb_stat -s id2v <db-path>
Just to be clear, the current upgrade doc is a bit paranoid. A 2.4 DB is forward compatible with 2.5. But 2.5 allows you to configure new DB parameters that would make it incompatible with 2.4.
Or another way to put it:
Unless sortvals, multival, or idlexp is being newly configured as a configuration change during the upgrade process, there is no requirement to reload a back-mdb database on reload with OpenLDAP 2.5.6 and prior. However it will not be possible to export this database via slapcat until after an OpenLDAP 2.5 slapd has been executed with the database in place. With OpenLDAP 2.5.7 and later it is possible to export a 2.4 database with slapcat in all circumstances.
