jameswnl / db_migration_plan_for_VDS
Created March 17, 2016 02:59
DB migration plan for VMware Distributed vSwitch support:
PR1:
1. update table switches.uid_ems = switches.host_id + "|" + switches.uid_ems
2. add index to switches on field uid_ems :uniquness => true
(VDS already has its uid_ems natural unique, this migration is to enforce that for local vSwitches)
PR2:
1. create a join table between hosts and switches, host_switches
2. populate (host_switches.host_id, host_switches.uid_ems) = (switches.host_id, switches.uid_ems)
