Question on switch-version and data loss

[Paul McGurn]

Hi,

In reading info around the web, I do find and understand that any changes made to configuration of an upgraded CUCM node will be lost if they were made after upgrade but before switch-version.  I was wondering if CDR files/database were also grouped into this, or if those are copied over when switch-version is executed.

Hi,

CDR records will be lost, only user facing features are preserved. Please check the following post

Thanks Manish.  Do you know if there's a similar write-up for Unity Connection?  I already know UCCX loses everything, based on experience.

Wow, that's a lengthy read.  Tnanks for the pointer, I'll have to set aside some time to process through that one.
