There should be few real changes to take into consideration: it's not like a
migration from a much-earlier version of Moin (like the recent messages about
1.5.x or, astonishingly, 1.2.x) where you might have to process the content
for Moin's parser to be happy with it or to upgrade extensions to work with

The Web server log is the thing to investigate here. I can think of a few
* Cached content (stuff which is pickled and doesn't always like being
unpickled in a different environment). Use "moin maint cleancache" to
deal with this.
* Generated .pyc files (that might not work in the new environment). Use
your favourite combination of "find", "xargs" and "rm" to deal with
* Permissions and policies (standard user, group and access rights plus things
like SELinux). See (for SELinux): https://moinmo.in/HowTo/FedoraSELinux
My "favourite" error was related to the i18n mechanism:
This should be mostly dealt with by the above measures.
