This article will provide solution when duplicate VMs and ESX hosts appear after moving the ESX hosts to another vCenter.
VMan creates duplicates when you move your ESX hosts to another vCenter or move VMs on to another ESX host. This is due to the change of the vCenter or ESX host identity on the VMAN server.
Remove the added vCenter or ESX hosts on the VMan datasource then run a manual database maintenance and re-add the vCenter or ESX host on the VMAN datasource:
Remove the vCenters or ESX hosts:
Note: Delete all entries on the datasource.
Run the VMAN manual database maintenance jobs:
Note: This will not remove or delete any historical data.
Re-add back your vCenter or ESX host:
Note: once you enable the collection jobs it will automatically run.
You will need to let the collection jobs finish so that VMAN will be populated with updated data from the datasources.
