	4	+We will migrate all the tfvc repos into one git repository called "migration" as a staging area to facilitate the process of moving the individual solutions into its final git location. This can be done in a delta fasion until we restrict the tfvc repos and everyone starts working off the git staging repo.
	5	+
	6	+Feature branches can be merged back into master via a pull request and the feature branches that are not applicable anymore can be abandoned.

	8	+= Migration process =

	11	+The process to sync the tfvc to the git repo
	12	+
	13	+1. pull all the latest changes from TFVC via cli
	14	+\\{{code language="powershell"}}tf vc workspace /new migration /collection:https://dev.azure.com/ebsphere
	15	+mkdir c:\dev\src\migration
	16	+cd c:\dev\src\migration
	17	+tf vc get{{/code}}
	18	+
	19	+1. do an extract and dump into excel to generate the copy commands
	20	+\\{{code language="PowerShell"}}forfiles /P C:\dev\src\migration /S /C "cmd /c echo @isdir;@ext;@path" >>list3.txt{{/code}}
	21	+
	22	+1. execute copy commands from excel generation
	23	+11. this will split the source into master and feature branches
	24	+
	25	+1. A recon step must be performed at this stage to make sure all files where copied this is performed in excel
	26	+11. get directory listing of copied files (dir/s/b %path% > list.txt) and dump into "recon" sheet and "recon" column in main sheet will indicate if any are missing with a 1
	27	+11. rectify any problematic items
	28	+
	29	+1. run the [[tf-sync.ps1>>doc:.tf-sync.WebHome]] script
	30	+11. this will parse the directories that was created into the migration repository
	31	+111. see [[mappings >>doc:.mappings.WebHome]]for structure
	32	+11. this will create or update the migration repository in GIT
	33	+11. an .gitignore gets injected this will make sure binaries are excluded
	34	+11. subsequent runs if the repo already exists will create a feature branch for the main branches timestamped with the date is was ran
	35	+ie: /feature/master-20220202-172700
	36	+

	38	+= Disable TFVC repository =
	39	+
	40	+After a repository has been moved to the staging environment and a call has been made to switch off the old repository we will put the old repository in read-only mode, the steps are:
	41	+
	42	+1. Notify the team and request that any pending changes need to be committed
	43	+1. Do a final delta migration of the repository
	44	+1. Disable inheritance on the repository
	45	+1. Remove Contributors group
	46	+1. Make sure the Readers group is present
