I have read all the article in this subject and followd all the steps.

When I run the migration tool it stops at 11.33% with the following error message:

[2009-09-23 08:21:31][Error] An error occurred migrating data in Object Store. The exception was:
System.NullReferenceException: Object reference not set to an instance of an object.

It is not possible to know what´s wrong, what is it exactly the tool does att this stage?

SQL tracing output

SELECT pkID as Id FROM tblItem JOIN tblIndexInt _pendingIndexing1 ON _pendingIndexing1.fkItemId=pkID WHERE fkSchemaId=5 AND _pendingIndexing1.fkSchemaItemId=31 AND _pendingIndexing1.FieldValue=1;

The format of the ObjectStore has changed from version 4 to version 5. Because of this the Migration Tool will try to load all objects from the object store, and then re-save them with the new format.

Did you follow the step about "Updating Blog Templates" mentioned in the Migration Tool Technical Note (it's the last step in list Preparing for Migration)?

Problem SOLVED!

It seems that I had a invalid item in the Schema with the id 15 "DefaultProducer", that was what I could figure out with the tracing.

I solved the problem by simply deleting the row in tblSchema and it´s items in tblSchemaItem.

I have no idea what "DefaultProducer" is byt I hope i chan live without it.
The migration then ran a bit moore smoothly.

EPiServer please improve your error handling in the migration tool!I just got the null exception pasted above.
