Can I safely upgrade Etch to Lenny (ISPConfig2, Drupal, Multisite)? Want mod_gnutls.

[tester321]

I have multiple Drupal 5.6 sites running well under ISPConfig2 using this.

I want to make sure there are no known issues if I follow this.

Why? The ONLY reason I want to do this is so that I can try mod_gnutls to see if I can get Multisite SSL on a single IP working ... since it appears to be very promising using this.

References:
1) Server Name Indication

2) SSL-enabled Name-based Apache Virtual Hosts with mod_gnutls

3) name-based virtual hosting with ssl

4) I don't want to have to do this (patching, recompiling, etc):

Thanks in advance for any thoughts, feedback, or suggestions. Sorry for any overkill, but I just want to make sure.

Yes, I am answering my own question

1) Followed HowToForge here to perform the Etch to Lenny Upgrade.

2) Works very well.

3) I did however receive this at boot:

Short name (NAME) undefined in /etc/default/sasl/authd, using default (warning).

4) The Fix is detailed here.

5) Note that you may also receive

Starting : defaultNo run directory defined for default, not starting failed!

This is also detailed in the same fix

Everything appears smooth so far, ISPConfig2, Drupal, Multisite. I will run the Upgrade utility in Drupal as well.

Now it's on to try mod_gnutls for this name-based SSL ... something tells me that won't be so simple.

PS, I am running this in a Virtual Machine
