[Zope3-Users] Resuming Zope use
Milind Khadilkar
We have used Zope a few years ago... had to stop rather abruptly... and now are attempting to get back into using Zope.
Most of the work we have done is in Zope 2.7.x, while some work dates from much earlier versions.
Is it right that we would need to install the *exactly* original Zope versions ( or is it *major* original Zope version?) to get our old work up and running?
If we want to reuse that work in Zope 2.13 and continue from there, is there a transition path without installing old versions?
We also have some work in Zope 3.1. Should we go in for BlueBream now?
What should be the Zope2 learning path for new entrants (fresh out of college, with fair Python knowledge)?
Advise would be highly appreciated.
With Thanks.

Those are broad questions that can not be answered seriously if you
don't tell us about the kind of application you have built in the past
with Zope and what kind of applications you intend to buildout with
Zope-ish technlogy in the future.

Actually we are looking for very generic answers, even hints, at this stage.... looking for a starting point, so to say. Something that would help us commence our study.
Our applications have mostly been small web based application prototypes which were meant to showcase Zope and our work in specific end-user domains and addressed small end-user problems. The aesthetics of the applications were, by and large, secondary. They were not websites and we had commenced them in 2.x because Zope 3 was not ready at that time. They were commenced in the period 2001-2004 and maintained through 2006-8. Had we written them *today*, from scratch, we would have used Grok, probably.
The development and deployment environments were MS Windows versions of the time. Now we plan to use Linux almost exclusively.
Most of them used DTML rather than ZPTs.
Most used script(python) extensively.
Some used ZODB exclusively, while a few others used RDBMSs alongside.
None of them used ZEO
They used third party Zope products very rarely
One application used SVG extensively.
Two applications were 3 person-years of effort, two others a one person-year of effort, and others were smaller.
We are planning to rebuild the smaller ones from scratch, using Grok.
The four larger ones we would like to migrate to Zope 2.11 using Python 2.6 (or to Blue Bream, maybe)
We have one application in Zope 3.1 which we would probably extend further in Zope 3.4 or Blue Bream.
What we have of them are .zexp and .fs files and some installation documentation.
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
The least we want to do is to reinstall the old work in a manner that we (especially the new programmers with us) would get to see it and take a decision on each application separately. If there is a way we can install the applications using the current Zope versions, we would love it.
Thanks and regards

As Andreas said, *no one* can give you any sensible help with the
information you provide. You should do the following:
- install your applications into a later version of Zope
- start it up and look for error messages or site breakage
- come back to zo...@zope.org (for Zope2) with specific errors you see.

Out of curiosity - and I'm biased of course ;) - what leads you to
consider Grok for the *smaller* apps and not so much for the bigger apps?
kind regards, jw

Because we already have taken pains on Zope3 configuration for them,
intending to port them to Zope3:). We did not get there though.
Actually, these applications are fairly intricate in terms of the
domain issues they handle. We feel good knowledge of the inner
structure of these applications would be good for developers to
have... Zope3 would "force" them to have that, I suppose.
There is also some sense of "solidity" (apart from awe) about Zope3
which I do not get with Grok.
But all this is based on my extremely limited understanding of the
three platforms today, compounded by a hazier understanding of the two
platforms of yesteryears. So I am likely to be totally wrong and am
open to knowing better.
Thanks, again.

Could you elaborate on that "sense"? Again, that's out of curiosity of
your perspective on Grok (you knew I was biased, right :) )
Perhaps even, you could express grok-specific concerns you might have on
the grok mailinglist too? Hmm, even though it might be useful for the
zope-users list as well, anyway... I'm still interested :)
