We are planning to move from TFS to VSTS. How do we migrate our data and is there a variance on license count or cost from one to the other?
Migration from Team Foundation Server (TFS or DevOps Server) to Azure DevOps has two aspects - data migration and license migration.
There is no automated way to migrate time records and time-related data from an existing TFS collection to a DevOps account. If you use recommended way of migrating data of your TFS (see https://aka.ms/TFSImportData) then all your Work Items data will be preserved upon migration and you will have 2 options of migrating Timetracker data.
You can either export/import data step by step yourself or you can provide the data to 7pace and we will do the migration for you.
7pace offers a paid service to migrate your data. Please refer to this article for further information: https://support.7pace.com/hc/en-us/articles/360000459966
In the first case, you need to first export time-related data from your original account and then import that data into the new account.
To export data, we recommended using the export feature available from the "Budgets" page (https://support.7pace.com/hc/en-us/articles/115000552903--Budgets-Page-Exporting-Tracked-Time-Details), or use the Reporting API (https://support.7pace.com/hc/en-us/sections/115001334706-Timetracker-API).
To import data, you can use the import feature available on the "Times Explorer" page (https://support.7pace.com/hc/en-us/articles/115000569206--Times-Explorer-Importing-Time-Records).
Migrating a license is not possible, as license application and types work differently (see https://support.7pace.com/hc/en-us/articles/115005445466-Can-you-explain-the-difference-between-buying-licenses-on-the-VS-Marketplace-vs-7pace-com-).
Timetracker for TFS licenses are sold on the 7pace store and are valid for unlimited TFS server installations, but cannot be applied to VSTS accounts (for Pro, Business and Premium plans). If you are planning to migrate from TFS to VSTS on an Enterprise plan or if you want to find out if there are any solutions for your specific case, please contact firstname.lastname@example.org.
