Hello,
Need some help in upgrading Plone from 2.0.5 to 3.0. I belive that upgrade
from 2.0 to 2.1 is a major upgrade. I just wanted to know if I can upgrade
from 2.0.5 to 3.0 directly or do I have to upgrade from 2.0.5 to 2.1 to 2.5
and then 3.0. Which path would be a better option? Can somebody provide some
pointers here?
If anyone has done the upgrade from 2.0.5 to 3.0, please let me know.
Rohit,
2.0 to 3.0 is a lot in one go, and hardly anyone has done that all at
once. If something goes wrong it might be hard to know where. On the
other hand, branding of 3.0 is so much easier and nicer than 2.1 or 2.5,
that it makes sense to go straight to 3.0, rather than waste time doing
re-branding on 2.5 for example.
The main things you'll have to fix are :
a) Customisations which may no longer work in versions later than 2.0
b) Third-party products that have not kept up-to-date well with Plone.
The more your site is customised, the more messy this migration could
be. It's probably best in your situation to "throw away" existing
customisations, just migrate content, and re-brand from scratch.
I recommend do 2.0 to 2.5 on a test machine and get it working (minus
customisations, in an unbranded state) first before trying to go to 3.0.
Try to test throughly and make sure there are no problems with the 2.5
site. If you do encounter problems here, at least you know it was
between 2.0 and 2.5 (probably between 2.0 and 2.1, because thats the
more difficult/messy step). Keep this system intact, so that if problems
occur on 3.0, you could go back later and check whether the same problem
existed at 2.5.

Hope this helps,
Nick
P.S At some points during this migration you may feel fairly, er,
"brain-fried", and start wishing you'd never chosen Plone. ;-) However,
this feeling will not last forever! ;-) It is worth the effort because
the later versions are a huge improvement on 2.0, and easier to work with.
