[support] upgrading to 5.8. One question.

[Brian Choc]

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.
