DFS hosting server migration

1. Login to destination server and go to G:\Applications\CERN\AdminTools\DFS\Migrations
2. run rbcpy.cmd \\source_server\share_name dest_disk:\dest_dir_case_sens logfile.txt
3. repeat previous action
4. check log with notepad logfile.txt to see if new files were copied and look for errors
5. if needed, fix access denied errors with \Applications\CERN\AdminTools\DFS\Migrations\Tools\SubInacl.exe tool. First revoke builtin\admistrator and then grant, e.g.: SubInacl.exe /subdirectories f:\Departments\Safety\Groups\RP\Instrumentation_Logistics\Back_Up\Backup_DPerrin_31-8-2006\C51\* /revoke=builtin\administrators
6. check number of connected users, their idle time, open files, open mode and types of files and eventually wait and go to step 2
7. share the folder using naming convention (e.g. D-IT-G-IS$) and set sharing permission to full control for everyone (we rely on filesystem ACL)
8. open DFS console: run dfsgui.msc, add New Target, uncheck "Add this target to the replication set", specify path to the shared folder
9. in DFS console, remove old target
10. unshare the folder on the source server
11. edit the page and detail of the move (source, dest, time)

DFS old hosting server migration

1. For each folder on a given machine
   1. make sure new copy is shared
   2. Stop the share on the old machine - from this moment people cannot access files)
   3. Make a final copy (it will take a while)
2. Make sure that you know local administrator password on the old machine
3. Disjoin the domain with the old machine and reboot it
4. Logon with local administrator account and change its name to something like oldname-old
5. Go to Nick and ask to
   1. Rename old machine to oldname-old in the LanDB
   2. Add a CNAME alias to new machine which should be called like oldname
6. Wait until DNS changes propagate
7. Check if the DFS folders are accessible
8. As a final clean-up - can be done later
   1. Update appropriate web page with the information on when and where folder was moved
   2. Change DFS links to use new machine name instead of oldname, which is now in fact an alias
9. remove old records from wins
10. apply http://support.microsoft.com/kb/281308 on new server (to support aliases for SMB)
11. put new server to the set in the webreq
