Migration Assistant - Catalina to latest OS. Can it be done?

I wish to withdraw my question. I mistakenly thought I read that both computers needed to be at the same MacOS level. However, further reading appears to claim they can be different. My only fear was an incompatibility problem I had previously encountered between different versions of Numbers. Data that was input using the latest version of Numbers actually disappeared when using an older computer with an earlier version of Numbers. Since I never had a problem accessing data input on the old computer running an older version of Numbers when accessing the spreadsheet using the latest version of numbers, my concerns seem to be unfounded. Thank you.
