[support] Upgrade to Drupal 5?

[Daniel Carrera]

Hello,

I have a production website that runs on Drupal 4.7. Should I move it to 
Drupal 5.2?

I'm concerned that migrating might be difficult, might be work, or might 
cause downtime for my users. On the other hand, I'm concerned about 
staying with an old software version that might become unsupported in 
the future, and that migration might be more difficult later.

My Drupal 4.7 site has several modules added on and I figure that these 
might not all work in Drupal 5. My understanding is that backwards 
compatibility is not a development goal for Drupal. So perhaps the best 
way to "migrate" is to essentially re-do the website from scratch and 
then copy all the content from the 4.7 site.

I'm generally happy with Drupal 4.7. Is there any page that briefly 
explains what's new and exciting in Drupal 5 that might make one want to 
move to it?

Any help would be appreciated.

Cheers,
Daniel.
