You can migrate as many times as you like, in between you can either roll-back, revert vRA8 to snapshots or just re-deploy vRA8.

Just be careful when you migrate the deployments, you cannot roll-back after migrating deployments. But you can then still revert to earlier snaphots of the vRA8 or just re-deploy vRA8 clean.

Also, as expected, when you migrate deployments and destroy a deployment in vRA8, the containing Virtual Machines are also deleted from vCenter. So my advice, don't migrate deployments and don't destroy deployments in vRA8 until you are completely ready to do so.

(there is a fix to remove migrated deployments without deleting the VM's in vRA8.4)

I migrated vRA7.6 to vRA8.3 and 8.4 many times (and then re-deployed vRA8 and migrated again) without any issues.

In the migration pages, you can select what to migrate.
