I have an upcoming project where I will have to go from XtraDB 5.5 to 5.7. I’m considering two ways… Upgrading 5.5->5.6->5.7 or doing a “logical backup” on 5.5 and importing in 5.7.
I have not decided on the best approach in my case.
I’ve noticed that XtraBackup 2.2 seems to be gone (as well as 5.5, but I am able to guess the download links for XtraDB 5.5).
Is the XtraBackup version important? I have a very old XtraDB 5.5/XtraBackup 2.2 that I want to upgrade to XtraDB 5.7/XtraBackup 2.4.
So can I use XtraBackup 2.4 wtih XtraDB 5.5, 5.6 and 5.7?
