Config Sync failure after installing Hotfix

Hi,

There are a couple of issues you are reporting here, but I think both may be resolved with a single action. Are you familiar with the 'cpcfg' command?

If you run 'cpcfg' while on the HF6 location, with the destination of the copy the HF13 boot location. You should be able to boot into HF13, however, you may still have some sync issues until the primary is also upgraded to HF13.
