The Better Choice: Drupal 6.4 or Drupal 5.10?

It is true that both versions are supported now, but support for D5 will be dropped when D7 is released. If you use D5 you will then need to decide if you should upgrade or perhaps leave your site vulnerable.

It is hard to predict which modules will be updated to the new version. Sometimes it makes more sense to start out with the newest version and less modules in order to put off the upgrade as long as possible.

> I found a lot of the modules available are only for version 5

You can't use an infinite amount of modules. Each one takes up memory and other resources.
So although there are 4000 D5 modules, you'll only be able to use 20-30 of them on one site.

So the questions become:

· which 20-30 features are you actually interested in?
· out of those, are there 'must-have' modules for D5 which haven't been released for D6?
· if so, are you willing to keep your site at D5 in the likely event that you cannot upgrade later?

Are you going to rebuild the site from scratch every two or three years?
If so, it might be worth using D5 now, and then rebuilding it in D7 in two years time.

At this point it's basically a function of what critical modules you need. I think the big ones that still require a d5 install are the ecommerce ones (ubercart and ecommerce) and possibly panels though I expect that one to progress rapidly now that there's active upgrade work going on.

If the Drupal-5-only modules that you want to use are crucial, for example if it is an e-commerce site and a stable e-commerce module exists only for Drupal 5, then go with Drupal 5.

If the Drupal-5-only modules that you want are just "nice to have", then go with Drupal 6. You may not even know whether those modules are ever going to be updated or abandoned, so you may be left behind. Before deciding to use a module check its history (the activity and dates of its issues queue and its CVS commits) and its popularity, except if you can support it yourself.

I am new in here, sometime i think, why Drupal must to release two different drupal version ?

If Drupal only have one Drupal version, so this problem will not happen. Example, if we say today
Drupal ve 5.14 and 6.8 version then one day Drupal will not release and support Drupal 5 version again, so Drupal release the 7 version.

My question is why Drupal must to release new Drupal version again whereas we have the Drupal 6 version ?

If we only concentrate with the current version, so this will not make the Drupal's user confuse to choose which version is more better to use.

Thanks.

As a newbie I started out with version 6, but soon realized that the e-Commerce module is solid only for version 5.

Here's the dilemma. When version 7 is released will module developers jump on the band wagon for version 7 and leave version 6 modules in the dust?

Let's say they have a version 6 beta module, then version 7 comes out. Is there a point to pursuing the beta 6 module or is it a wiser decision to go straight into development for version 7?

Looking down the road it would seem that a Drupal users are going to face tough decisions. If the solid module release is for version 5, a beta version for 6, but the developer drops development for the version 6 module and pursues version 7, which Drupal version then becomes the best choice? Use 5 and have your site less secure? Use 6 with some of the modules still in beta? Or hope that module developers concentrate on version 7?
