[Zope] Re: Advice on upgrade?

[Jean-Francois.Doyon at CCRS.NRCan.gc.ca]

Ah, I'd wondered whether I could safely do that ... Just never really knew
exactly how
tied to a version an instance might be ... There could be changes in the
ZCML for zope.conf
for instance? ... Which is why I decided to to do it this way.

Good to know the option is there though ... Maybe I'll do that next upgrade.

Or maybe you also need to edit the paths in bin/runzope 
and bin/zopectl.

But I wouldn't take that approach at all.
One nice thing about instances is that you don't have to tie them
to a particular release and you shouldn't have to edit anything
when you upgrade.

What I do is this:

1) install zope in a versionless directory, e.g. in your example
/var/zope

2) cd /var/zope and create your instance, e.g. in your example:
/var/zope/bin/mkzopeinstance.py
and name the instance something like:
/var/zope-instance  (again, no version number)

3)  mv /var/zope /var/zope272
4)  ln -s /var/zope272 /var/zope


Having done all that, your future upgrades will be easier.
E.g. when zope 2.7.3 comes out, you can install it in /var/zope273
and then do:
ln -sf /var/zope273 /var/zope

and you're done.
No changes in your instance necessary.
