Can I use the same username when installing a new version of LM and keep my files?

hi,

I am currently on linux mint 20.2. I will install linux mint 21.2 victoria.

My quesion is during the installation where it is asking to create a user, can I use the same user name 'dave' from linux mint 20? And if I use the same user name 'dave' will all my files and config files still be there in /home/dave? or will it erase everything?

Thanks in advance.
