photo database compatibility with different versions of Lightroom Classic

[bobbyb1951]

I use two Mac's for my photography.  I used a 2019 MacBook running Monterery 12.6.6 for printing only.  It has Lightroom Clsassic 13.5.1 and Photoshop 26.0.0 installed.  I recently got a 2024 MacBook for all other uses including photo editing.  when I plugged my external drive containing my photo files into the 2024 MB and started Lightroom Classic version 14.1.1 LRc wanted to update my photo database.  I quit before that occured.  my question is if I allow the database to be updated will the older version of LRc (13.5.1) work with those updated files?  thanks for any guidance you can give on this.

Are you using the same LrC V 13.5.1 on both machines? Either way, the update to V 14.x will create a new catalog with all the information from the older one, but it will not be usable in V 13.
