PHP4 to PHP5. 2 additional questions.

[lanschue]

Hi,

i'm planning to update our plesk 8.6.0 server (on Debian etch) from php4 to php5, and found most needed information in http://kb.odin.com/en/1762.

But still 2 questions keep me from upgrading, because there are many websites of customers on this server and I have to avoid downtimes at all costs:

1) When trying to simulate the upgrade with

apt-get -s install psa-php5-configurator libapache2-mod-php5

It tries to deinstall the packages "ppwse" and "php4-ioncube-loader", so as i don't want to loose any packages (although I don't really know, if i need above 2 packages) I would try to update with

apt-get -s install psa-php5-configurator libapache2-mod-php5 php5-ioncube-loader ppwse

But still this leaves me with many broken packages (according to "man apt-get"), as you see in the output:
(Sorry for the german output, but should be readable anyway)

The broken packages in square brackets are "psa" and "ppwse".
So are only mentioned, because there will be unresolved dependencies during the installation-process but after installation everything will be ok, or will the installation really result in brocken packages?

2) If some of our customers rely on php4, is it possible to switch back to php4?

I think a

apt-get install psa-php4-configurator libapache2-mod-php4 php4-ioncube-loader ppwse

should do it. But just to get sure, i wanted to ask, if anyone has ever tried this.

Would be nice, if anyone could help me on this two questions, before i have to try it. (The server is not even in our city and downtime would be very very bad.)

Thanks in advance.

Hello lanschue, I'm in the same situation. Did you do the upgrade anyway? How does it result?

solution

doing this got me closer, but still errors.

i did the thing where upgrade to php5 and uninstalls all this plesk stuff. really annoying. right now i've moved beyond the 'Problems found: could not find pleskctl' to plesk more nicely telling me that 'The Plesk Control Panel service is switched off' which might just mean that it's installed.
