Copying map from alpha 12d into alpha 15c

[whoami]

Hello, long time ago in RimWorld - version: alpha 12d (0.12.914 rev777) I have started a colony, and found a great spot to make base in mountains.
Now in RimWorld - the newest version: alpha 15c (0.15.1282 rev1150) I would like to use my old map, to make a new colony.

I know that, I should copy the map seed from older version into newer, and it should look the same but it does not.

I don't know if something changed in generating map.

And my question: Is it possible to generate the same map in the newest version of RimWorld, of course with new resources (like components, jadeit etc.)?

This is the map file from 12d version of RimWorld:

I will be very grateful if you will answer my question.

Best regards,
