Re: [Xen-users] XCP pool upgrade

[George Shuklin <george.shuklin@xxxxxxxxx>]

The different version of xapi (we talking about xapi, when talking about 
XCP upgrades) can coexist together, but only with extremely limited 
capabilities. This mode intended only for live pool migration from old 
hosts to newer one to allow seamless upgrade of platform without 
interrupting guest VMs operations. During that mode you need to avoid 
any management operations (like sr creation, vdi resize, new vm creation 
and so on). Only shutdown, may be start and migrate.
You can met some troubles with guest tools (outdated version), but this 
can be easily solved by 'faking' guest version (talked may times in this 
maillist and described on wiki pages).
But just in case be ready to 'worst case' scenario: shutdown all VM and 
start them back after upgrade.
