[support] upgrading to 5.8. One question.

Mon Jul 14 18:34:31 UTC 2008

Yes, that was my recollection from a few months ago. It was definitely CCK related (which, I believe doesn't have a uninstall function: very few modules seem to) and I certainly lost data from merely disactivating, not uninstalling.

Needless to say, I learnt my lesson and won't be doing the same again.

  I found that disabling modules during minor upgrades causes data loss consistently under specific circumstances, during earlier updates (e.g. 5.2, 5.3).  I observed that any module-supplied node type would drop all the data in any assigned CCK fields when disabling & upgrading.  For example, if one had a simplenews node with an "editor" cck field attached to it, one would lose all "editor" information.  However, the basic simplenews node data would be kept, as would any cck fields attached to standard nodes.  Only the combo of cck + module-supplied-node-type seemed to cause problems.

  Fortunately, I make backups before upgrading and restored each time and did the upgrade without disabling modules and it worked fine.  After 5.5, I think, I gave up attempting to disable modules and have had no problems since.

    I believe I made a mistake. The case where I lost data I think was
    actually that I uninstalled a module.

    You are correct, because simply disabling module does run any code, so
    how could any data be lost?

    It indeed should be the case that disabling modules will NOT lose any data.

    My mistake for saying otherwise.
