How to handle VSSConverter UserMap.xml files for users who no longer exist

When running the VSS to TFS converter (VSSConverter.exe) one of the most common questions I hear is how to create a UserMap.xml file for users who are no longer with the company or have had their accounts renamed.   My first suggestion is that any customer who has to deal with this issue (or any…

WSS Rant - finding out what changed is much more difficult then it should be. (Lessons 4 and 5)

In my previous rant I made this statement (quoted out of context): Migrating WSS content to TFS?  Piece of cake.  Just enumerate each WSS change and replay the action in TFS.  If you are doing an incremental migration then just enumerate those changes that have occurred since the last time you checked for changes. There…

hexadecimal value 0x07, is an invalid character

Every once in a while I get a message that at first baffles me but once I understand the problem it’s hand-smackingly obvious.  This error message was one of those.  “hexadecimal value 0x07, is an invalid character” By now I’ve run into this problem a few times and with a few different converters that target the TFS version…

How long should a version control migration to TFS take?

I’m curious what you think. Imagine you have an installation of Generic Version Control System with 500,000 items you intend to migrate to TFS.  Each item has, on average, 3 revisions of history.  So you have 1.5 million revisions.  And let’s say that this was done over 200,000 changsets.  Also, if you want, let’s say…

Time travel, 20 questions and the power of free soda.

Yesterday I presented 20 questions that I think are a good starting point when designing or evaluating a version control migration product.  The point is basically to get folks thinking about what should be migrated, how it should be migrated and what would happen if that data were not there. Last night I conjured up…

Writing Version Control Migration Tools - Handling Namespace Cycles

Last time I discussed the issues surrounding namespace conflicts when designing a version control migration tool.  The basic lesson was that there are times when operations must be executed in a specific order for them to migrate properly.  But what if there are namespace collisions for which there is no order that resolves the collision?…

Writing Version Control Migration Tools - Handling Namespace Conflicts

Migrating from one version control system to another is tough.  I don’t care what the internet forums are saying or what Joe from down the hall told you.  It’s hard.  Very hard.  Deceptively hard. The obvious algorithm looks trivial: FOR EACH Changeset CS in History DO      FOR EACH Change C in Changeset CS DO…
