I have tried unsuccessfully to migrate my Lightroom 5 catalog to the new Classic CC.
Everything I read tells me to install a trial of Lightroom 7, update the catalog; then I should be about to migrate the newer version of the catalog.
Is it still possible to install Lightroom 7? I can't find it.
Or is there another option?
You must subscribe to a 'Photography' plan to upgrade to LR-Classic CC (v7.3 just released)
You install or update Lightroom Classic-CC by using the Creative Cloud Desktop App.
LR Classic-CC is currently otherwise known as Version 7.3 (There is no Version 7 Perpetual 'stand-alone')
To 'Update' a Catalog (LRCAT file) you can Double-click the Catalog used in LR5 to 'open' it with LR-Classic-CC 7.3 and a copy will be made, the copied catalog updated to work with LR Classic-CC v7.3, and "-2" will be added to the updated Catalog name.
(Note: an updated Catalog for LR-Classic is not backwards compatible with LR5, but you have the original LR5 catalog untouched, backed up- i hope!!)
