Admin/TheBigMove

On the 21st February, 2006 Skynet will move from 136.201.105.0/24 to 193.1.99.64/26. This will break *everything*. This page details how we intend to fix everything.

To do

Beforehand

  1. Ask ITD to _actually_ setup the static route.

  2. Setup joshua as the new firewall with either unnumbered routing or bridging.

  3. Add flexo to new network and test.

  4. Cleanup DNS and get everything ready to move

  5. Find all IP addresses in all configs and change (where possible) to service based names (ASAP)

On the day

  1. Change all IP addresses

If we have time:

  1. Migrate /home to the sata raid array

  2. Re-cable the rack

  3. Put GigE cards in skynet and orac
