Migranting only Mysql 4 to 5 on Sugar 4

[rmazili]

Hello,

I want to migrate my mysql version 4 to 5, but I'm using sugar 4.0.1c and I don't want to migrate it too, just my database.
Is it possible without problems like driver version, and libraries?
If so, do I need to change anything in sugar source code or configuration files?

Thanks

I don't remember when MySQL 5 became officially supported, but in theory, I would think it would work as long as you don't change your PHP setup.

Don't forget to make a backup before the upgrade!
