First of all, I'd like to thank you for making such a terrific product. In the end, it worked very well and saved me many (more) hours of frustration, after struggling with another method of porting to x64. I did have a bit of trouble with the export / import process that I thought I'd share for the benefit of others.
After a successful export with the migration tool, the import hung driving the java process to 100% cpu utilizaion. The last line in the import log file was:
ExternalRestore INFO Adding item xxx
Where xxx is the item number. In my case it was 269. I tried importing again and it hung at the same item. I tracked that item down in the export file system and found it was a contact. Upon looking at it in the source Zimbra instance, I noticed that it had an image associated with it so I deleted the image and re-exported. The import past item 269 successfully but hung on a different one. Guess what? Another contact with an image. After removing images from all contacts and re-exporting, the import worked perfectly.
Here is some information about my environment.
