Have a read of the following support doc - "Migrating Native Users and Groups Via Lifecycle Management (LCM) Fails (Doc ID 1379619.1)"
For EIS you can install on 32bit OS and then you should be able to export/import, then you can point the 64bit to the relational db, alternatively it may be possible to point to the existing db as I doubt anything much has changed with the EIS database structure between those versions.
I see same error with either of the options but users are imported in Destination env. Any leads or your findings appreciated
1. Share services - Import after Edit option
2. LCM utitlity.cmd with XML file defination
