Have anyone upgraded Oracle Webcache from 10.1.2 to 11g with configuration upgraded as well (webcache.xml) ?
I can not find any documentation on how this can be done - only how to install new Webcache.
What I did find was a note on Metalink that says how to copy a webcache.xml from one install to an other install:
How to migrate configuration files from one Web Cache site to another [ID 222280.1]
But this does not say if format has changed from 10 to 11.
AFAIK, there is no upgrade strategy from 10g to 11g for Webcache product as a standalone component. Apparently, Oracle Web Tier utilites is tightly coupled with these components [OHS + WLS + Webcache] which is managed through Oracle Enterprise Manager console as a part of OFM 11g.
