There is no record semantics conversion process in Koha.  There are
scarcely any preconfigured tools available anywhere to convert all
possible data between UNIMARC and MARC 21.  Automatically retrieving
commonly available records from a different MARC semantics would be easier
to implement than complete conversion between UNIMARC and MARC 21.

Even if your existing records are simple enough to convert easily, purging
the installation and recreating a small number of records would be trivial
in comparison to what would be required for a comprehensive conversion
between UNIMARC and MARC 21.

Create a new installation for MARC 21 with a new database name.  If
reusing the database name, then drop the database before installing.

I leave it for someone else to report again about how to purge the Zebra
index completely without leaving any phantom index information.  Sometimes
special magic seems to be required without deleting all of the files
commonly placed somewhere under the /var directory which relate to Zebra.
