Subject: [PATCH] Issue 4877 - RFE - EntryUUID to validate UUIDs on fixup
0a5078
 (#4878)
0a5078
0a5078
Bug Description: Due to changing the syntax of EntryUUID's
0a5078
to string, we may have invalid EntryUUID's imported into
0a5078
the database.
0a5078
0a5078
Fix Description: To resolve this during a fixup we validate
0a5078
that Uuid's have a valid syntax. If they do not, we regenerate
0a5078
them.
