Etch->Lenny upgrade w/o losing Postfix virtual hosting?

Hi Falko

I'm running your awesome debian lenny virtual server postfix+mysql+clamav+amvis+etc on my colo'd server. Working Great and has been for over a year.

I now need to upgrade to Lenny (Etch support ending) and I'm really concerned that upgrading will blow away at a minimum the PostFix-MySQL changes for all the virtual hosting.

Can you give me any words of wisdom on doing that upgrade on a production system especially regarding preserving the funcationality and data of the postfix+mysql setup?

Thanks again,
JK

 

Just to add more info, I setup the server using this great tutorial of yours

"Virtual Users And Domains With Postfix, Courier And MySQL (Debian Etch)"

 

If you upgrade, you must rebuild Postfix according to http://www.howtoforge.com/virtual-users-domains-postfix-courier-mysql-squirrelmail-debian-lenny . Or you set Postfix on hold:

Code:

echo postfix hold | dpkg --set-selections

 

Just to clarify, if I upgrade postfix along with everything and don't patch it, all I lose is quotas? That is, all the other configuration changes I made to have postfix use MYSQL etc will still be in place and it 'should just work'? I don't have to go thru the HowTo you referred to for Lenny and redo all the configuring?

I miss remembered and was thinking that the postfix patches were part of allowing it to use MYSQL.

Thanks again.

 

Yes, that's right.
