Hi, 

when old data is opened, a "LEGACY PGP" icon appears in the top right-hand corner of CATIA. 
The graphical properties can then be migrated. Depending on the status, this can be migrated by the user or admin. 

DS also provides documentation and a utility program (CATPrdPGPPMRMigrationBatch) for this purpose. 

What happens during the migration (what is changed) and can we ensure that this data will continue to work after the migration?  In addition to the PGP migration, there is also the PMR migration. Here, too, the question is whether this can be carried out "without any problems" or whether data can be lost.
