Migrating from VNET (Classic) to ARM has interruption on the resources?

Herbert Rodriguez 20

Have a good day,

Migrating from VNET (Classic) to ARM has interruption on the resources (apparentaly not) ?, Also in case something goes wrong there's a rollback for this change ? we don't want to have issues with the services. the following link is what I have for this migration:

https://learn.microsoft.com/en-us/azure/virtual-network/migrate-classic-vnet-powershell

anyone has done this before without an issue?

kind regards

@Herbert Rodriguez ,

Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.

I see Marcin Policht shared the details.

As mentioned ,

There isn't a data path downtime during migration - only control plane downtime where you will unable to perform CRUD operations on the resources.

Post migration, all management operations can be performed using the Resource Manager model.

You cannot revert once you commit the migration - There shouldn't be any issues as long as you adhere to the Prerequisites and Supported scenarios

Please let us know if we can be of any further assistance here.

Thanks,

Kapil

The migration will have impact on the control plane operations (i.e. they won't be available during migration). It should not affect data plane operations (e.g. network traffic between VMs on the VNet).

You cannot revert once you commit the migration.

This does work as intended as long as you satisfy the prerequisites.

For details, refer to https://learn.microsoft.com/en-us/azure/virtual-machines/migration-classic-resource-manager-faq

You can abort your migration as long as the resources are in the prepared state. Rollback is not supported after the resources have been successfully migrated through the commit operation.
