Convert to APFS for Catalina upgrade

Hi to everybody! I have a MacBook pro and recently tried to upgrade from Mojave to Catalina but i got a message that the volume i use is not formatted as an APFS. The strange thing is that i use already Mojave and during the previous upgrade from High Sierra to Mojave the volume didn't changed to APFS as in many other users. My problem is that i open the disk utility and when i select the Volume, the option "convert to APFS" is grey and cannot be selected. I tried to restart and open from there the disk utility but i still got the same message. Is there any solution? Cause without converting to APFS i cannot upgrade to Catalina

Yes you can convert on the fly.

Apple provides non-destructive methods for start-up disk drives for APFS conversion, and hence no data (files or folders) will be lost. On the other hand, APFS formatting will erase all the files and folders stored on the external hard drive. If not backed up earlier, APFS formatting on the external drive will cause data loss. Even with the start-up drive, one may delete or lose files from the APFS formatted media.

Non-Destructive APFS Conversion

Restart the Mac into Recovery Mode.

Launch Disk utility.

Click-select your named boot volume—the default name is Macintosh HD —(Not the physical drive above it.)

In the Disk Utility> Edit menu> select “Convert to APFS"

This is a surprising fast conversion. It is always recommend to have a current back in the odd circumstance something goes sideways. I have heard of no issues here.
