Import Data error (Export from BC, Import to BC CU 01)

Hi all how to export import data file?

both are the same objects (either CSide object or my own extension object)
I want to export - import our demo data
how to resolve this?

it will not work. the import and export to a datafile only works when the import and export database are on the same version. What you are doing is really not a backup, and should never be treatead as a backup.

Your best possible solution is to use RapidStart…

so for the posted data (cust ledger, gen ledger ,etc) cant be migrated?

If you have a Dynamics Partner License then yes.
