Earlier in the thread you mentioned R75.40VS, but just now you mentioned R75.40.
These are very different versions (and require different tools), so which is it?
If you're just planning to use the same version, then you have to get this right.
The approach I would recommend is installing R77.30 Gaia and importing the configuration from your R75.40/R75.40VS manager using the R77.30 Migration Tools to perform the export/import.
We do offer an IPSO version of this tool.
This will get you to a base that is currently supported at least.
