64bit upgrade from Buster to Bullseye

[Falcon-118]

Yes, from what I know so far, this is not officially sanctioned... However, I have been through several builds of GPS NTP servers with PPS and for some reason, they all fail when initially built on Bullseye. The good news is they build up fine on Buster... both 32bit and 64bit. I have one of each running and would really like to bring them up to Bullseye. I've watched and or read many processes for this upgrade but no one seems to delineate between 32/64. Is there any difference in the upgrade process?

Thanks in advance for any help or answers.

The upgrade process from Buster to Bullseye for 64-bit and 32-bit systems is essentially the same. However, it's crucial to ensure compatibility of packages and dependencies for your specific applications, and thoroughly backup before upgrading. Always refer to Debian’s official upgrade guide for the most accurate procedure. Keep in mind that upgrading directly from one stable release to another is generally supported by Debian, but any issues you encounter with specific software may require additional troubleshooting.

Upgrading should work with no problems.
Be sure to take a look at https://www.debian.org/releases/stable/ ... ase-notes/

And keep in mind that the official method for rpios is doing a clean install.
