I recommend running Bitcoin Knots instead of Core. I have upgraded with the single line:
sudo rsync --ignore-times rsync://peer.dedyn.io:1873/knots/* /usr/local/bin
Bitcoin Knots uses the same files format so blockchain re-download is not needed.
Bitcoin Knots is more powerful and higher quality node implementation. There are more instances of the Bitcoin Knots v. 20250305 than any Core version older than 28.0 (according to clarkmoody.com).
