There's some serious issue with the migration script, however.
I have imported and renamed the JoomDOC 2 tables. JoomDOC 3 can see them. The relative file path to move files from is correct.
Still, not a single document is migrated.
Table j25_sefurls backuped as j25_sefurls_joomdoc3_migration_backup. There was replaced DocMAN/JoomDOC2 URLs with JoomDOC3 URLs.
Imported 0 DocMAN/JoomDOC2 categories as JoomDOC3 folders and 0 DocMAN/JoomDOC2 documents as JoomDOC3 documents.
Somebody in a German speaking forum has bumped into the same roadblock. To bad my scarce knowledge of the language is not enough to fully understand how the poster fixed it.
