Old issue, big problem

I have an iMac2017 and have just migrated the OS, applications etc to an SSD in an effort to prolong the life and speedup of this computer. I can open Resolve (had to reenter Activation Key) and it shows some projects but not all. More crucially, it doesn't show my most recent. I've been trying for hours to find this most recent project. Nothing shows in Open Recent.
Under Resolve_Backup/Resolve Project Backups, I can see some files that I'm sure are related to this project but can't open them. I've used Finder to pickup all the .db files but cannot find it.
Sorry I know this is a frequent issue but I'm stumped, I cannot find the project.
Can anyone offer some help on finding lost projects please.

I made a video 1 year ago about one related issue, but not sure if it can be useful for you.
I work in Windows.

Thanks Victor, my problem is a little different, I’m sure the project is in the original file structure in a new first level folder (Apple renamed Macintosh HD to a new name on the SSD) but I don’t know what file I’m looking for or even how to use DR Project Manager to look for it. I know the Project name but nothing resembling a project file turns up. I’m baffled.

On Windows, if you open the Project Manager you can display the left pane containing the list of databases (by clicking on the split window icon just to the left of "Projects" at the top left corner of the window).

You can then click the circled-"i" Information icon next to your database (i.e., "library") name and click "Open File Location" to go directly to the folder containing the database.

On my system, if you go from that folder into the subfolders named "Resolve Projects", then "Users", then "guest", then "Projects" you'll see the projects that are in this database.

I have to say, though, that I've always treated the contents of a database folder as a black box and not to be mucked around with.

Thanks Sean, you got me halfway but this video by Jason Yadlovski was the clincher. Very useful info. I've now recovered one project and will proceed with the rest tomorrow. The feedback here and this video has given me much more insight into the file management system in Resolve.
