I was too lazy and immich-go may not have existed when I migrated but I just selected and downloaded my pictures from Google Photos then just uploaded them to Immich and they seemed to keep all their metadata.

I couldn’t agree more, I join selfhosting communities all over and not just because I need more stuff to host, because of the community. I love getting to read through the questions and answers, even when they are questions that could be answered by just reading the man page… Maybe it just reminds me of the good old days as I’m getting older and remember asking a lot of similar questions.
