When migrating to IM or Nimsoft it will be necessary to keep NV around for reports on historical data.
By default NV will expire devices so to retain the data follow these steps:
At each system disable discovery and the Polls service.
Console > Config > Discovery > click the box 'Periodic Discovery Enabled' so it is deselected and then click Set.
Console > Services > Polls click Stop.
Console > Config > Polling > click the box 'Polling enabled' so it is not selected.
Additional steps to ensure data is retained:
Console > Config > Polling > go to each dataset and
at the Dataset tab make sure the 'Polling Enabled' & 'Periodic Discovery Enabled' check boxes are not selected and then click Set.
at the Retention tab increase the retention for the rollups.
