Hi All,
Have just had a frustrating time migrating a site, both in terms of
version and platform, and physically.
I am a (very happy) Zettai customer, and whilst the Zettai set-up is
great the amount of memory on the "webmaster" package is limited, and I
know from experience that the tactic of exporting a site in a "zexp"
file (which is pretty shaky anyway, or rather the import of Plone sites
this way is) is a no-no at Zettai because the system runs out of memory
during the import process. The memory allocation at Zettai is not a
problem in normal use - just during imports.
So, I have downloaded a 2.04 site in a full "data.fs" from a Windows
server, mounted it using the ZODB mount point trick, and run the
migration to 2.1 locally, so that I don't hit the memory limit at Zettai.
In the process, I've learned a couple of things which may be of use to
others: -
1) There is a bug or documentation issue WRT mount points, which means
that if you simply use the documented notation in the zope.conf, your
data.fs will mount - but it's content will not be visible. The relevant
bug report is at: -
http://www.zope.org/Collectors/Zope/1487
Long story short - make the name of your mount point the same as the
name of the folder or folderish object you want to access, or use the
syntax at the URL above.
Using this technique, you can perform your migration locally, and upload
the ".fs" to Zettai, eliminating the need to overcome ".zexp" import
problems, memory-related or not.
2) In my migration, I got an error indicating that an object in a member
folder would not migrate, but the error pointed only to the folder. On
examination, the member in question had a favourite pointing to a (now
deleted) CMF Board forum. After deleting the favourite, the migration
proceeded without (apparent!) error.
This seemed counter-intuitive to me, as the "favourite" was a "normal"
type, even though it pointed to an "abnormal" (!) one.
Hope this helps somebody...
