I am upgrading a site from Drupal 6 to Drupal 7, following the instructions here: https://www.drupal.org/node/570162
When running update.php it gets stuck on the first step ‘Updating user module’ at 0%. I’m wondering if this might be because the site has about 400,000 registered users (another issue there I need to fix), or if something else is going on to prevent it from updating. Perhaps the message
Notice: unserialize() [function.unserialize]: Error at offset 416 of 427 bytes in variable_initialize() (line 935 of /services/webpages/util/5/4/54ev547u.myutilitydomain.com/livemusicashland.com/ifollo/public/includes/bootstrap.inc).
has something to do with it? It’s my first attempt at updating from one major Drupal version to another, so I’ll take any advice I can get. Thanks!
