Phase 1 -- upgrades 'in place'

1. nimisrvc: universal swap-out node
   • install slf5, postgres (Maurine)
   • install nimi,Zope software (Marc)
2. nimisrv:
   This is the test run for migrating all the other boxes, so is expected to take twice or better as long.
   • migrate dev Zope and Soap startups, etc. to nimisrvc
   • migrate postgres databases to nimisrvc
   • Check/back out/retry
   • install slf5, postgres (Maurine)
   • install nimi,Zope software (Marc)
   • migrate databases back
   • migrate dev Zope and Soap back
3. nimisrva:

Phase 2 -- migrate to have db-only boxes.

1. Prd application move
   • migrate Zope,Soap instances nimisrva -> carnac (other box?)
   • move nimisrva IP address to carnac/other-box

   • after a week (for broken DNS caches), turn off/drop nimisrva IP.
2. Dev database move
   • install postgres on nimisrva-devdb
   • export/import databases nimisrv -> nimisrva-devdb
   • fix nimi development configs to point to nimisrva-devdb
   • restart development
   • deinstall postgres from nimisrv
