Tfs to tfs migration tool

They tend to be of the form…. In the long run, some of these scenarios are best served by direct support in the product and we are working on that for our Rosario release. This tool is delivered on Codeplex with source code see the link in the last paragraph. It enables:. Lest you become too giddy at the prospect, it is not a perfect solution and some of the limitations of this approach make it less than ideal for some of the scenarios I listed above.

Here are some of the key issues to think about when deciding how to use this tool:. You don't have to upload any files, and you can skip this step.

This can be an existing container or one created specifically for your migration effort. It's important to ensure that your container is created in the right region. Azure DevOps Services is available in multiple regions. When you're importing to these regions, it's critical to place your data in the correct region to ensure that the import can start successfully.

Your data must be placed in the same region that you'll be importing to. Placing the data anywhere else will result in the import being unable to start. The following table lists the acceptable regions for creating your storage account and uploading your data. You can't import your data into other US Azure regions at this time. You can create a blob container from the Azure portal.

After the import has finished, you can delete the blob container and accompanying storage account. AzCopy has multithreaded upload support for faster uploads. A shared access signature SAS key provides delegated access to resources in a storage account. The key allows you to give Microsoft the lowest level of privilege that's required to access your data for executing the import.

This is essential, because the data migration tool does not support account-level SAS keys. Do not generate an SAS key from the Azure portal. Azure portal-generated SAS keys are account scoped and don't work with the data migration tool. Select Use a storage account name and key , and then select Connect.

On the Attach External Storage pane, enter your storage account name, provide one of your two primary access keys , and then select Connect. On the left pane, expand Blob Containers , right-click the container that stores your import files, and then select Get Shared Access Signature.

Write and delete permissions aren't required. Earlier in the process you partially filled out the import specification file generally known as import.

At this point, you have enough information to complete all the remaining fields except for the import type. The import type will be covered later, in the import section. In the import. You do this by allowing connections only from the set of Azure DevOps Services IPs that are involved in the collection database import process. The IPs that need to be granted access to your storage account depend on the region you're importing into. Use the IpList option to get the list of IPs that need to be granted access.

Alternatively, you can also use Service Tags in place of explicit IP ranges. Azure Service Tags are a convenient way for customers to manage their networking configuration to allow traffic from specific Azure services. Customers can easily allow access by adding the tag name azuredevops to their network security groups or firewalls either through the portal or programmatically.

Imports can be queued as either a dry run or a production run. The ImportType parameter determines the import type:. Dry-run imports help teams test the migration of their collections. Organizations are expected not to remain around forever but to exist for a short time. In fact, before a production migration can be run, any completed dry-run organizations will need to be deleted.

All dry-run organizations have a limited existence and are automatically deleted after a set period of time. Information about when the organization will be deleted is included in the success email you should receive after the import finishes.

Be sure to take note of this date and plan accordingly. Most dry-run organizations have 15 days before they're deleted. Dry-run organizations can also have a day expiration if more than users have a basic or greater license at import time. After the specified time period, the dry-run organization is deleted. You can repeat dry-run imports as many times as you need before you do a production migration.

You need to delete any previous dry runs before you attempt a new one. When your team is ready to perform a production migration, you'll need to manually delete the dry-run organization. For more information about post-import activities, see the post import article.

If you encounter any import problems, see Troubleshoot import and migration errors. Your team is now ready to begin the process of running an import. We recommend that you start with a successful dry-run import before you attempt a production-run import.

With dry-run imports, you can see in advance how an import will look, identify potential issues, and gain experience before you head into your production run.

If you need to repeat a completed production-run import for a collection, as in the event of a rollback, contact Azure DevOps Services Customer Support before you queue up another import. Azure administrators can prevent users from creating new Azure DevOps organizations. If the Azure AD tenant policy is turned on, your import will fail to finish. Before you begin, verify that the policy isn't set or that there is an exception for the user that is performing the migration.

For more information, see Restrict organization creation via Azure AD tenant policy. A common concern for teams that are doing a final production run is what their rollback plan will be if anything goes wrong with import. This is why we highly recommend doing a dry run to make sure that you're able to test the import settings you provide to the data migration tool for Azure DevOps. Rollback for the final production run is fairly simple. Before you queue the import, you detach the team project collection from Azure DevOps Server or Team Foundation Server, which will make it unavailable to your team members.

If for any reason you need to roll back the production run and bring the on-premises server back online for your team members, you can do so. You simply attach the team project collection on-premises again and inform your team that they'll continue to work normally while your team regroups to understand any potential failures. If you don't complete this step, the import will fail. In the event that your import fails, see Troubleshoot import and migration errors.

You start an import by using the data migration tool's import command. The import command takes an import specification file as input. It parses the file to ensure that the provided values are valid and, if successful, it queues an import to Azure DevOps Services. The import command requires an internet connection, but does not require a connection to your Azure DevOps Server instance.

To get started, open a Command Prompt window, and change directories to the path to the data migration tool. We recommended that you take a moment to review the help text provided with the tool. Once dependencies are moved into NuGet, make sure that they will not be included in the Git repository by adding them to. Team Foundation Version Control provides a. This can be used for automatically generated files like build output so that it is not accidentally checked in. If the project relies on this behavior, convert the.

Cross-platform TFVC clients also provide support for a. Check in any changes that remove binaries, migrate to package management, or convert version control-specific configuration. Once this final change is made in TFVC, the import can be performed. Follow the Import repositories documentation to actually perform the input. Git-TFS is appropriate to attempt a migration with full history, more than the days that the Import tool supports, or to attempt a migration that includes multiple branches and merge relationships.
