Migration of collab.mcs.anl.gov on 2015-05-02

As part of our plan to merge the contents of Confluence running on xcollab.mcs.anl.gov and collab.mcs.anl.gov we will be moving https://collab.mcs.anl.gov/ to https://collab.cels.anl.gov/ and upgrading the Confluence software from 4.3 to 5.7.1
This hostname migration will occur late Saturday May 2nd (2015-05-02). During that time, it will not be possible to update or add pages to your Spaces on https://collab.mcs.anl.gov/.
Once the migration is complete, the site will be replaced with a link to https://collab.cels.anl.gov/ and will eventually be brought off-line entirely.
Once https://collab.cels.anl.gov/ is up and the migration is completed, users browsing the old address will be shown a notice directing them to the new address.
During the following week we will work individually with owners of Spaces hosted on https://xcollab.mcs.anl.gov/ to migrate them to the new server as well.
