best updating algorithms j2.5 to j3 and vm2 to vm3?

[vm3newb]

Hello,


I've an eShop on j2.5 which has a VM2. I would like to both upgrade to j3 and to VM3. Now I'm not sure how best to approach this. My guess is that as VM2 is not compatible with j3, I must first upgrade to VM3 on my existing j2.5, then after a successful upgrade, go for the j2.5-to-j3 upgrading step.

Please make me clear

Correct
J2.5/VM2.6->J2.5/VM3

then
J2.5 -> J3

Correct
J2.5/VM2.6->J2.5/VM3

then
J2.5 -> J3

Thank you, I went to start upgrade, then I navigated to Virtuemart 2 – Live Update, then clicked "Update to the latest version". I got these messages:
JInstaller: :Install: Cannot find XML setup file
Invalid package type. The update can not proceed.

I see these informatio in the live-update page:
Installed version 2.0.26d
Latest version 2.6.6

Now should I manually try to install from 2.0.26 all the way to 2.6 stable, then from there to VM3? Or there is any simpler way, like just take VM3 files and try to install as an extension?

Do not use the live updater! It has been removed for current versions. See http://forum.virtuemart.net/index.php?topic=123808.0

You can go direct from VM2.0.26d to 2.6.14 and then to VM3.0.3 (or 3.0.4 which will very soon be released).

All this should be tested on a backup copy of your site, not on the live site! If you use a commercial template or template overrides then these may need editing to work with VM3.

Thanks a lot! I'm here alive with finished migration of VM2 to VM3 and J2.5 to J3! I'm not sleeping? ;-)
Well, still on a test server:

One last question:
Sure my template is gone! Now I have to make a new template from scratch. I know how to design template for J3 (bootstrap based), but I've never created a template for VM.
Is there any guideline or simple tutorial (meaning even very brief) where I can have a starting point please? any documentation regarding VM templating please?

P.S.
Welldone VM creators! I didn't believe it before doing it: how simple it was! All crystal-clear steps, no bothering warning / error, etc. Congratulations for such a mastery!

Use the default VM templates - ie rename the [Joomlatemplate]/html/com_virtuemart directory. That gives something that should work. You say you are going to migrate then to Joomla 3.3 which will require a new Joomla template, so I'd leave making any required VM template overrides that you may need until that migration is done.

but I wrote in my post: I'm done with all migrations! if you click to the link of my test web site you'd see, it is now fully on J3 and VM3, so I'm exactly to know about those VM template overrides!

Could you please tell me, how I should start making a template for my new VM3 on J3?

it is very simple .. as Jenks said it is just over rides

ONLY over ride what files you need -- your just shifting VM frontend views->tmpl files into

templates/your_template/html/com_virtuemart/productdetails  etc

basic how to's here

http://docs.virtuemart.net/tutorials/templating-layouts.html

but also as he says - decide what your Joomla J3 template is first -- what people sell as VM templates is a joomla template with some over rides for the VM view files

Thanks very much! In fact I already wrote J3 bootstrap-based templates, also J3 extensions, but never done so with VM, I wanted to start from examples to learn not only of templating (overrides) for VM but also how to extend it and searched Amazon for books over "programming" VM, but there found only simple shop setup books. I'd follow links you kindly sent.
