Upgrade from J1.5 to J3 - CB Profile Gallery not updated

Hi,
I am updating CB from Joomla 1.5.26 (before 1.0.15) to Joomla 3.4.8 before I move on to J4.
in Joomla 1.5.26 I have the two tables:
jos_comprofiler_plug_profilebook
jos_comprofiler_plug_profilegallery

I use SP Upgrade on Joomla 3.4.8 to conntect to the database and migrate the comprofiler tables.
However my plugins Profilebook and Profile gallery are not migrated. They are missing in the 3.4.8 database.
Can I just export them in 1.5.26 (CB 1.9.1), change the table prefix from jos_ to the new one and import them in 3.4.8 (CB 2.4.7), then install the new plugins to migrate?

Thanks
Sigrid

That might work, but I can't say for sure. We don't have a migration protocol for CB 1.x anymore as it's 7-8 years old at this point.

CB ProfileGallery doesn't exist anymore as well. It's replaced by CB Gallery. CB ProfileBook still exists, but is in maintenance mode now as it's replaced by CB Activity and core CB Blogs.

It seems it has worked for the profile book.
But for the gallery, it says it migrated but I cannot see the galleries in the backend.
Or is that expected behaviour?

Hm, or is there a table missing?
like utsar_comprofiler_plugin_gallery
Or should there be some entries in utsar_comprofiler_plugin_gallery_folders?

CB Gallery media is stored in _comprofiler_plugin_gallery_items. You should see the migrated media in CB Gallery > Media, but again you're dealing with 7+ year old code and I've no clue if this will even work let alone work smoothly. It's just the danger of letting an install sit unmanaged for so long. We don't test migrations that far back.
