We are preparing to do a large migration from SharePoint 2010 to SharePoint 2013. The site structure will be changing radically. Reading all the documentation it mentions the site structure has to be identical on both servers. Has anyone done something like this? I am assuming I would need to create the new site structure in the SP 2010 environment, move the workflows into the appropriate places using the NWAdmin tool and then perform the migration? Are there any great 3rd part tools to assist with this? I would like to keep all the workflow history and make sure any running workflow continues to run in SP 2013.
The first thought I have about this is to ask: exactly what sort of structural changes are you talking about? If it's topology, it shouldn't be quite so difficult, but it's still a big topic. Generally you would be best to follow other documentation on this site about moving sites etc around, but be aware that there can be issues with content types when moving data around.
If you want to use the migration process to reorganize SharePoint data, we would generally say that it is not a good idea.
Overall, you essentially would need to reorganize data either in the original environment pre-migration or in the destination environment post-migration, using already published methods that should be in this site.
Thanks Cameron! I agree it is a very complex topic. We are planning on doing a few pilots to see what is possible. I would be happy to share my experience as I suspect this is not an uncommon scenario.
