Subject: Re: [Zope] 2.6 to 2.10 migration: RuntimeError: maximum
Importing as zexp? If yes, this is unsupported.
Yes, I imported the Product as zexp. Why is that unsupported, and how
else may I import it? It doesn't exist in the filesystem hierarchy, as
it's a custom Product which was developed in the ZMI.
Or is there a save way to export the Product from the 2.6.4 instance to
files and then import the files to the 2.10.3 instance?
Typically Zope 'Products' exist on the filesystem. If you created your
product entirely thru the ZMI, then you probably have a ZClass-based
product. These type of products can be exported but not directly imported.
If you tried to import it you should see a broken product icon in the
Control_Panel/Products listing in the ZMI.
There is a work-around: you can create an external method which can import
the 'exported' zclass product, something like:
prdDir = self.unrestrictedTraverse('/Control_Panel/Products')
Note: ZClasses are officially deprecated as of Zope 2.10. They may work or
they may not, but they are no longer officially supported.
