You are using GitHub as a source control solution for an Azure Synapse Studio workspace. You need to modify the source control solution to use an Azure DevOps Git repository. What should you do first?

When changing the source control repository type or provider in Azure Synapse Studio, the existing connection to the GitHub repository must be disconnected before a new connection to an Azure DevOps Git repository can be established. This ensures a clean transition between source control systems.

Creating a new pull request is an action within the current source control system (GitHub in this case) and is not a prerequisite for changing the source control provider itself.

Changing the workspace to live mode refers to deploying changes from the Git repository to the Synapse workspace for execution, which is unrelated to switching the source control provider.

Changing the active branch is an action within the current Git repository and does not facilitate switching the source control provider from GitHub to Azure DevOps.
