I am trying to migrate from TFS 2013 Update 4 to Visual Studio Online. I have had real difficulties using OpsHub Migration Utility, so I have come now seeking advice on how I may go forward.
I have 65 Team Projects to migrate, some with source code, others fairly empty with just a few work items so they differ in size a fair bit. I want to maintain branches we currently have which are cross Team Projects so I initially tried selecting all 65 projects for migration. This took 11hours at the creating configuration stage of the utility, then on getting to the end the tool complained it could not communicate with the service OpsHub Visual Studio Online Migration Utility. So back to square one.
Next approach was to batch the projects into sets of 10 projects. The validation and creating configuration stage was done in 10mins for each set which was a big leap forward, and the migration actually started. This has currently been running for about 17hours. It has done 29,000 work item revisions out of 480,000 across all Team Projects, so I think this may well take a couple of weeks to clear. It hasn't started on the Version Control data yet, which I'm hopeful it does at a later stage but this says not running at the moment.
This is running on a fast i7 box, with 16GB RAM, SSDs the business. 100Mbps internet connection.
I have emailed OpsHub to find out if the commercial version will perform better. But any suggestions what I could do better welcome, including any alternatives to the migration tool.

For Configuration creation taking high time, the assumed reason seems to be due to issue in communicating with the service OpsHub Visual Studio Online and waiting till the TimeOut.
The Work Item migration sync time seems to be near to the expectation, migration of Version Control data will be started once the work item migration is completed.
Also as the data is in big amount, its taking time but the migration would keep on running in background, you can use your source TFS instance(if required) without stopping the migration.

There is another tool named TFS Integration Platform that developed by MS for TFS Migration. You can try with it to see if it can migrate the data faster.
