Can I run two multi-store migrations at the same time?
Unfortunately, it is not possible due to technical reasons. To prevent any possible faults, please, wait until one migration is completed and then proceed with the next one. In case you are moving from one shopping cart that supports multi-store to another, you can perform a single data transfer for all substores by simply mapping them at Stores Mapping section of "Entities Selection" step.
