user account renomming/changing access way

Hi

2 cases about modifying user account:
* how do you handle user account renaming ?
said, i have a svn account with htaccess.
i want to change the username ? how can i keep the history ?
* if i want to change access methode, say apache to ssh, keeping same
login will do it or else ?
Short, is svn using login as identity or uid or else ?

thanks a lot
Regards
