v2t migration cleanup failed with an error "Failed to delete Org VDC networks"

At this time the nsx v2t migration is completed and I'm running the final touch which is cleaning up the source Org VDC and I encounter the below issue.

Here is the actual error: Error: 2023-07-24 08:14:16,685 [vcdNSXMigratorCleanup]:[run]:230 [ERROR] [Org Name]| Failed to delete Org VDC networks ['VLANID_1350'] - as it is in use

Moving forward with the v2t cleanup we need to fix the issue first. Today I will share this to you :)

Steps:

• First get the network lnet_id to get that Login to Provider vCD > Cloud Resource > External Network > Click the specific network in questioned

• In this screen capture we can see the network lnet_id. Take note of that

Note: We need to manually cleaned-up the referenced network entries from DB post taking the database backup.

• SSH Primary Cell, login as a root

• Type "sudo -su postgress psql vcloud"

• Type \x so that you have good display

• Here are the commands run to clean-up the db

• Type delete from network_interface where lnet_id = 'f4b6151a-510a-4958-950b-79053eb2836a'

• Type delete from logical_network where name = 'VLANID_1350'

• Try to re-run the nsx migration tool to cleanup the source Org VDC

• Post which the migration cleanup run successfully as expected

Note: This is my personal and owned experience that I love to share in the VMware Community. I hope you appreciate it, thank you
