Migrate from SingleNode to MultiNode orchestrator instance

Hi ALL,

We have a single Node Orchestrator instance which is connected to a Azure SQL Server DB.
We would like to move from a singlenode instance to a Multinode instance, we would like to use the current instance as the primary node. So do you have any documentation or step by step instruction to do the same.

We have gone through the link
[The Windows Installer](https://Multinode install)

but this instructions is for a fresh install of a primary node.

Any help would be really appreciated.

Please respond if you have any questions or clarification on the ask.
