How to migrate from MySQL 3 to MySQL 5 (installed from sources)

How to migrate from MySQL 3 to MySQL 5 (installed from sources)

Hi.

Working on Linux, I've got installed MySQL 3.23.58, but I'm
experiencing some problems. For instance, I suffer "too many
connections" error but I cann't set 'max_connections' parameter to a
value bigger than 250.

I decided to migrate to MySQL 5.0, and I've got some questions:
- I installed MySQL from sources on '/usr/local/mysql'. Is it as easy
as installing it again on '/usr/local/mysql5'?
- what must I back up to migrate data? '/usr/local/mysql/var' directory?
- is there any tutorial/webpage to carry out this migration?

Thank you very much.
