user_username max lenght

[alex916]

I'm transfering an old mail server to a new debian ISP server.
I found a little limitation.
In mysql database, the field user_username in isp_isp_user is varchar(32).
I configure ISPconfig with prefix [domain]_ and now i have some user with a username that could be longer to 32 letters.
If i change, in the database, the field user_username in varchar(64), i 'll have problem in the future?

Thanks and sorry for my english.

There should be no problem as long as you change the lenght of the field in the mysql database dump that is part of the ISPConfig installer to varchar(64) too before you update your system the next time.
