So the recommendation is to upgrade from 1.6.6 straight to
1.7.0-19 now?
I think we need to set a timescale for getting dCache sites
upgraded to a release of 1.7.0 soon. And start using SRM 2.2.
What are the main obstacles for sites to upgrade (other than
lack of time?) - that would be something to discuss under
item 1 in the phone conf tomorrow.
Good stuff.

Hi,
I've added some upgrade information to the wiki.
http://www.gridpp.ac.uk/wiki/DCache_upgrade_1.6.6_to_1.7.0
This documents using YAIM to upgrade your system. It is also possible to
just upgrade the rpms by hand and then run the
/opt/d-cache/install/install.sh script.
Cheers,
Greig
