New Post: Changesets missing after migration

Hey Matthijs,

I'm really glad to hear that you worked it out. Unfortunately, we are not allowed to take source code back from the community. Your welcome to start your own CodePlex project and post whatever changes you want there.

If you were able to determine why you were getting conflicts, I would be very interested to hear that.

Thanks
Curtis

Status update 2: the migration did _NOT_ succeed, as i ended up with more files in the new project than in the original.

Status update: i did some changes to do automerging first, (my migration is from a project, to an empty project) and now everything seems to work fine (now in the process of catching all versions, and comparing them). Will let you guys know. Are you interested in getting back the changes?

Regards,

Hi Curtis,

Thanks for your response. Sorry I didnt answer you earlier, but I didnt have access to my work pc.

I cannot disclose the logfile, as it contains source control pathnames, which contain sensitive filenames.

I did some further investigation, and it seems it's detecting conflicts. This seems weird to me, as i'm doing migrations to an empty project. Is there a way to have the tool always take the source file version, and overwrite the destination file?

Regards,

Matthijs ter Woord

Commented Issue: Source code migration stops midway without error

curtisp — Sat, 11 Oct 2008 05:34:52 GMT

Migrating source code from TFS2005 (SP1) to a TFS2008 (SP1) server. Migration gets through about 2/3rd the way, then ends as complete (no error). The trace file is attached.
Comments: ** Comment from web user: curtisp **

It looks like the last Changeset that it migrated was 4025. It looked at Changeset 4037 but it didn't find anything in there that was in your mappings.
If you go a history query on the path(s) that you map do you see changesets that go past that? Were these changesets maybe added since the tool was started?

Hi Matthijs ter Woord,
Can you please post the Trace File form the migration. It should be in the tool's install directory. This will be a huge help in investigating your error.

As far as speeding it up, theres not a whole lot you can do short of moving it to a faster computer. Please keep in mind that the tool will download every version of every file on the server then upload it again to the other server. That's alot of disk io and network traffic.

Thanks
Curtis

Hi,

We're in the progress of migrating a project (still doign dry runs for now, thankfully..). the tool seems to work nicely, except that it doesnt migrate all changesets!

what's the problem here?

Edit: during the migration, I often get:
TfsToTfsMigrationToolUI.vshost.exe Error: 0 : The item $/MoveTest already exists.
    LogicalOperationStack=Migrate
    ThreadId=16
    DateTime=2008-10-10T12:52:57.4997405Z

other q, how to speed up the tool? on a small playground project, it takes 30minutes to run

Regards,

Matthijs ter Woord

BTW, its the last conversion in that file. There was an earlier attempt that I didn't clear. Sorry.

Rated 2 Stars (out of 5) - I'm trying to move a single branch from one Team Project on one TFS server(TFSServer1) to another Team Project on a second TFS server (TFSServer2). I've tried creating the same Team project with the exact same name "WCW" but I can't get the source code to move over. Maybe this functionality isn't available yet....please add it soon.

Rated 2 Stars (out of 5) - I tried this tool again against out TFS instance that has been upgraded to TFS2008 and while initially it looked like it was working to migrate the source respository, it failed. I've deleted the migration database, unistalled the tool, and reinstalled the tool, and the migration continues to fail. The tool has improved from the previous version but it just doesn't work yet. Maybe the next version

I've tried to set up a WIT migration session (using TFStoTFSMigration 1.1) between two MSF Agile projects. Source is a TFS 2005 and target a TFS 2008. The session is stopped manually after a number of attempts and it fails with "synchronization engine has crashed".

New Post: Will the version control items will be migrated along with its "history"?

vineetsharma — Tue, 30 Sep 2008 05:36:23 GMT

Hi All,

Can anyone put light on the above topic, is it possible to retain the history of version control items while migration from TFS 2005 to TFS 2008?

Here is an image to the changeset details. I wasn't able to find a copy method to get the text directly. FYI, this used to convert correctly with the previous version of the tfs2tfsmigration tool. We've just never completed the process due to problems with another project that was started as a branch from this project.

The migration thread throw this exception when it trys to process a changeset for check in to target server. Can you find out which changeset is being migrated? If the changeset is not too large, can you paste the detailed changeset information?

Thanks,

Reviewed: TFS to TFS Migration Tool v1.1 (Prerelease) (Sep 24, 2008)

vikkuu — Wed, 24 Sep 2008 13:45:24 GMT

Rated 4 Stars (out of 5) - New Release (Sept 08) is much better in terms of migration of version control and WI. With this I migrated TFS 2005 to TFS 2008 with 100% source code. But I have few suggestions (may be included in future release) - Migration utility required both the src and destination TFS must be in the same domain. - Installation need named instance both of these were there in previous release(March 08).

New Post: Trying to get around credentials issues

jazzcatone — Mon, 22 Sep 2008 23:37:12 GMT

It states in the prerequisites for the tool that credentials should be the same for both the source and the destination server. This is pretty limiting being that many times we would like to migrate accross domains. (where credentials are passed with the domain info or the credentials are just different) Did anyone come up with any workarounds for this ? Keep in mind that I don't want to stand up another TFS instance just to do the migration. Any help or consideration would be greatly appreciated.
