Do you still have VSE/VSAM recoverable catalogs ?

VSE/VSAM recoverable catalogs are no longer supported on z/VSE 4.3 and z/VSE 5.1. Recoverable catalogs need to be converted by the customer or will automatically be converted to standard (non-recoverable) catalogs.
In earlier z/VSE releases VSE/VSAM provided recoverable catalogs, indicated via an optional parameter during catalog definition.
It caused that all records were written to a catalog recovery area (CRA). In case of a physical device error the failing tracks could be marked as "unusable", the user catalog would be rebuilt and the data copied from the CRA. Because of new DASD technology this function is no longer necessary. Therefore we removed that support in z/VSE 3.1, but existing recoverable catalogs could still be used in z/VSE 4.1 and z/VSE 4.2.
My recommendation is to convert recoverable catalogs to standard catalogs before you migrate to z/VSE 4.3 or 5.1.
However, if one or the other recoverable catalog is not converted after you are on z/VSE 4.3 or 5.1. VSE/VSAM catalog management will automatically convert recoverable catalogs to standard (non-recoverable) catalogs. This will be completely transparent to user applications.
On z/VSE 4.3 please make sure that APAR DY47322 is applied.
I assume your target system is on the latest service level anyway, that is you will have the conversion enhancement included.
