I currently have macOS Mojave on my 2015 MBP.
When I try to upgrade to macOS Monterey I get the message: "This volume is not formatted as APFS."
Disk Utility identifies HD as : Samsung SSD 960 EVO 1TB
Please explain to me how do I upgrade to macOS Monterey?

I'm saying it may convert it, it did here, but can't remember which upgrade did it.I think Catalina was the first OS to demand APFS.
I provided links for both above already...

Well, if you don't wish to see if Installing Catalina or Big Sur converts it automatically to APFS then you'll need an external drive to backup or clone your current drive to so you can Erase the internal drive.
Oh, have you encrypted the drive using FileVault?
Are you saying that I can install Catalina or Big Sur to get my drive converted to APFS?
If that is what you are saying, how do I do that?
Where can I download Catalina or Big Sur for free?
If you haven’t figured it out yet, I’m not a technical person. So please keep it simple.
Thanks for your help.
I have Mojave, not Catalina.
An auto upgrade is not working.
Can anyone walk me through the steps needed to upgrade to Monterey?
Which exact Mac do you have?
Have you tried Catalina or Big Sur?
Trying to install Catalina or Big Sur did not convert my drive to APFS.
I still get the message “This volume is not formatted as APFS”
Then you'll need an external drive to backup or clone your current drive to so you can Erase the internal drive to APFS.
