I am upgrading to PSE 2021 from PSE 4.0 (yes, it's been a while!).
I've done a Full Backup of the content on the old computer (WinXP running PSE4.0) to an eternal hard drive and have then plugged the external drive into the the new PC (Win10 running PSE 2021) and run Restore Catalog.
The restoration has worked except for the fact that the old catalog (*.psa format) has not been converted to the new PSE 2021 format (I believe the filename should be *.pseXXdb). It simply created a new *.psa file.
Additionally, if I point PSE 2021 (via Manage Catalogs) at the *.psa file, it cannot "see" it.
I have read all the help files and many posts on this forum about catalog issues, but to no avail.
Am I missing a step somewhere or are the PSE 4.0 catalogs unable to be read/restored by PSE 2021?
Any help would be much appreciated as I am trying not to lose years of careful cataloguing of various photos.
