ACL maps missing after manual migration


We have installed the packages from 8.0 to 9.5 (manual export and import).
Everything is fine and running well in new env. except the ACL maps.

All the execute/read/write ACLs were reverted to Inherited. This is hindering the integration test with external partners.

Could you please help me in exporting the ACL maps from 8.0 to 9.5 ?
