Can I or How do use the catalog from older LR 7.5 to work with LR 3.1
Need help, here is my situation. I have tried to find an answer with no luck, so I am going to ask here. I'm an intermediate user on Lightroom. I just moved to a new Win 10 PC. My old machine was Win 8, so I was running LR 7.5. Running old Windows 8 and the subscription indicated the newer versions of LR were incompatible. This year I get a new machine running Windows 10. With the creative cloud subscription and Win 10, it will only allow me to install the new LR 3.0 or 3.1. My question is Can I or How do use the catalog from older LR 7.5 to work with LR 3.1 when I can't get either machine to the current or earlier versions of LR? Can you point me in the right direction? What would be my next steps? Do I have to rebuild the LR 3.1 catalog? All photos and 7.5 catalog are on an external drive.
I have been using LR since 2012 and only as a hobbyist. Never have had problems with different OS and different LR versions like this.
Thank you in advance for any help.
