NSX ALB Virtual Service Migrator v1.2: Cutover and Removal of Prefixes

In this article, we will discuss the usage of NsxAlbVirtualServiceMigrator v1.2 to migrate virtual services from one NSX-T cloud to another. We will cover the cutover and removal of prefixes processes.

Prerequisites

Before proceeding with the migration process, ensure that you have already performed the following tasks:

* Set up the source and target NSX-T clouds

* Configured the same IP address space for both clouds

* Created a replica of the source virtual services in the target cloud

* Migrated the virtual services using NsxAlbVirtualServiceMigrator v1.2

Cutover Process

Once the migration is successful, we need to perform a cutover to switch over to the migrated virtual services. To do this, follow these steps:

* Disable the existing virtual services in the source cloud

* Enable the migrated virtual services in the target cloud

* Ensure that all traffic is directed to the migrated virtual services

Removal of Prefixes

After the cutover, we need to remove the prefixes appended to the objects during migration. To do this, follow these steps:

* Run NsxAlbVirtualServiceMigrator v1.2 in remove_prefix mode

* Select the run ID of the migration job

* Wait for the job to complete

* Review the output file to ensure that there are no errors

Cleanup Process

If at any stage of the migration process, we need to perform a cleanup of the migrated objects (either because the tool encountered an error or because the post-migration validation failed), we can run the tool in cleanup mode. To do this, follow these steps:

* Run NsxAlbVirtualServiceMigrator v1.2 in cleanup mode

* Select the run ID of the migration job

* Wait for the job to complete

* Review the output file to ensure that there are no errors

Conclusion

In this article, we have covered the cutover and removal of prefixes processes of NsxAlbVirtualServiceMigrator v1.2. We have also discussed the cleanup process in case of any errors or validation failures during the migration process. With these processes in place, you should now be able to successfully migrate your virtual services from one NSX-T cloud to another.
