In Promis.e SELECTseries 8, when trying to migrate a Legacy Symbol Catalog such as from Promis.e 5.05, 5.06, AERO I or AERO II, the following warning message occurs:
WarningSource catalog is not an ACAD catalog, please select an ACAD catalog.
This message occurs because Promis.e V8i SELECTseries 8 does not support migration of Legacy Promis.e data prior to Promis.e 2007. Promis.e V8i SELECTseries 7 (08.11.12.137) is the last version to include the ability to migrate data from promis.e 5.0x, Aero, and Aero II.
You will need to migrate the old Legacy files to a Promis.e version that supports those formats. The most recent version of Promis.e to support the older Legacy files is Promis.e V8i SELECTseries 7 (08.11.12.137). Once you have a compatible Promis.e version installed, you should follow the steps from the Migrating Legacy Data To promis.e article to migrate the legacy files.
Once the files have been migrated successfully in the compatible Promis.e V8i version, they can be moved to Promis.e V8i Selectseries 8.
