Upgrade from original Lightroom 6 to subscription Lightroom classic.

Question

Hi everyone, I am trying to open my old catalog from the original Lightroom 6 in Lightroom Classic but it doesn't let me.

When I do it comes up with this

The Lightroom catalog named "Lightroom 1Catalog" cannot be opened because another application already has it opened.

I do not have it open in any other app to my knowledge

Any help would be very much appreciated thanks.

And there is an Adobe Help Blog that describes the process as given by @DdeGannes https://helpx.adobe.com/lightroom-classic/kb/lightroom-error-catalog-cannot-be-opened-lrcat-lock.html

DdeGannes · Answer

Check the folder that contains your Lightroom 6 Catalog and if there is a file that has the same name as the Catalog with the extension .lrcat.lock (LRCAT.LOCK).

Delete the .LOCK file then you can double-click on the Catalog 6 file that ends with the extension .lrcat (LRCAT) and that should open the Catalog and prompt for you to agree to upgrade. A copy of the original Catalog will be converted to the upgraded version of Lightroom Classic.
