[xwiki-users] migrating from mssql to mysql

Hi guys, just a quick question? Do you think it will be difficult to migrate from a MSSQL database to a MySQL database. I have to use MSSQL for now, but might have the chance to switch from Micro$oft to Unix/Linux later and it would be very critical to do the mentioned database switch then. Any experiences or opinions around? Thanx guys. Cheers Sebastian
