Upgrading 3.4.8 -> 4.5.5

[SIUAviation]

Hello everyone!

In the process of upgrading from a currently heavily used 3.4.8 on Drupal 6 to Drupal 7 (succeeded no problems). Now I'm in the process of upgrading from CiviCRM 3.4.8 to 4.5.5, using the steps outlined here: http://wiki.civicrm.org/confluence/display/CRMDOC/Upgrade+Drupal+Sites+to+4.5+-+Drupal+7#UpgradeDrupalSitesto4.5-Drupal7-11.RuntheUpgradescript

I've recreated the civicrm.settings.php file using the install method, then changed the DB settings to the right database. When I go to /civicrm/upgrade?reset=1, the page loads just fine. Gives the right message, "Use this utility to upgrade your CiviCRM database from 3.4.8 to 4.5.5. "

When I click upgrade now, the page loads saying CiviCRM upgrade tasks, but the first line listed shows "[]" with the retry and skip buttons on the side.

Any thoughts or ideas?

Edit:
Supplemental, but I'm sure it's due to the need for an upgrade...

Speaking as the proud owner of a 4.4.11 install that when I first inherited it was a 4.2.6 install, I feel like I'm qualified to give advice on upgrades:

1) Don't do so many major releases at once. Go from 3.4 to 4.1.*, then 4.2.*, then 4.3.*, then 4.4.*, then 4.5.* (where * is the highest number for that release). This way your database schema will always be up to date.

2) It sounds to me like this is a configuration issue with how your civicrm.settings.php file is set up. Does it match your Drupal settings.php file. If you get really stuck with this it may be worth asking a consultant to do it.

Yes, that error is due to the not-yet-upgraded database not matching the codebase.

When I click upgrade now, the page loads saying CiviCRM upgrade tasks, but the first line listed shows "[]" with the retry and skip buttons on the side.

This means your JavaScript files are not loading. You can try deleting your templates_c cache and NULLing your domain settings with this:

Code: [Select]

UPDATE `civicrm_domain` SET `config_backend`=NULL ;
and try again.

If it still fails, then using a smaller jump as JohnFF suggested, is also a very good idea.

Will try these suggestions! Thanks!

I also get the error now when just trying to enable or disable the CiviCRM module...

This is getting frustratingly bizarre.

I think that the CiviCRM module is somehow disabled, but shows as enabled in the system. I cannot get to the upgrade page anymore, says page not found. Now getting this error when going to change the module settings of CiviCRM.

Code: [Select]

If you have not upgraded your database, then you need to use the OLD version of the CiviCRM code because that's what matches your database. Switch your code and it should work.
