WHAT DO YOU NEED TO DO?
Save and close any open files on AdminFS, the Windows home directories, or the Commshare prior to 5:45am.  
Close out of FileMaker Pro and any other affected applications.  
Users with affected Linux home directories should save their work prior to the maintenance period and be prepared for service interruption during the maintenance window.
Any manual backup or restore jobs with the CrashPlan servers that have not finished before the maintenance will need to be restarted after the maintenance period.
Users should avoid sending mail to Mailman mailing lists during the maintenance period.  Mail sent to mailman lists during the maintenance period may not be queued and may need to be resent.
