Yes,
we have several ZMS installations built on ZMS 2.12 and a few in "beta" status 
on 2.13.

hmmm,
im highly interested too here as it allows to "package" a Zope / ZMS 
installations and ZMS 2.12 / 2.13 brings very interesting new features we 
still rely on in different projects.

Unfortunately it seems to me that there are a few things still not really 
stable within 2.13 and even 2.12 as in older versions - i.e. under longer high 
load (including ZMS writes - without workflow) there are ZOPE / ZODB crashes 
sometimes. It seems to that newer ZMS are more sensible here to programming 
bugs i.e. within own objects / extensions or templates as they may lead to a 
complete crash of the ZOPE / ZODB instance. Activating / using cache seems to 
rise such "collisions" too.

Migrated ZMS instances to 2.13 or 2.12 often get a problem with the user / 
access management - it is not possible to edit / save any user record (i just 
get a field "content" with no error when try to save new or modified users). 
Fopr me it seems that the upgrade mechanism is not working properly in all 
cases here.
 
There are a few other small things which could be a "bug" - i.e. the Explorer-
Frame seems not work in any browser as before and there are some functions 
which seems not allow the usage of a non standard HTTP port (the port part is 
not processed properly within VirtualHost configs).

May be this is related to the fact that i use Unix / Linux hosts as afaik ZMS 
devels mainly use Windows machines or that i did anything incorrect here.

My possibly subjective experience here is that ZMS >=2.12 are a little bit 
"slower" then typical 2.9 / 2.10 instances we run - related to the fact that 
the newer (much more flexible) ZMS concept usually relys on more HTTP-requests 
per page then older ZMS.

I'm happy about any help or hint about this topics here or open in help 
troubleshooting here...

Yes, id did this - even for my own developed ZOPE apps as ZMS instances too.

But it takes a little to read and/or try to get all the required additional 
components installed to run a "typical" ZMS installation and/or want to 
migrate an older one.


best regards,
