Synchronizing from the new consolidator could cause duplicate CIs in the CMDB, because the consolidator will generate its own keys, which may not match the ones that were used by the scanner to sync with the CMDB.

To avoid this, export the root node keys from the scanner and import them to the consolidator. For reference, see https://docs.bmc.com/docs/display/DISCO113/Moving+node+keys.

Basically, the steps are:
1) Deploy the new consolidator, but do not connect it to the scanner yet.
2) While no scans are running on the scanning appliance, Stop All Scans from the UI.
3) From the scanner command line, run the following command:

tw_root_node_key_export appliance01_key_info.xml

When prompted, enter the password for the UI "system" account.

4) Transfer the /usr/tideway/appliance01_key_info file to the consolidator.

5) From the consolidator command line, run the following command:

tw_root_node_key_import appliance01_key_info.xml

When prompted, enter the password for the UI "system" account.

6) Disable the CMDB sync on the scanner
7) Enable the CMDB sync on the consolidator
8) Connect the scanner and consolidator
9) Start the scans on the scanner
