4. How many LPARs can be migrated at one given time?

Live Partition Mobility requires coordinated movement of a partition's state and resources. Migratable partitions move between capable, compatible, and ready systems.
A single HMC can control several concurrent migrations. There are no architectural restrictions on the number of migrations that can be underway at any one time. However, a single mover service partition can handle a maximum of four simultaneous active migrations. It is possible to have several mover service partitions on a system. In practice, the maximum number of concurrent migrations is limited by the processing capacity of the HMC and contention for HMC locks.
Taken from IBM's LPM FAQs.

There is also another link on that site that might be interessting:

Thanks. That's exactly what I was looking for. Looks like going for 10G NICs won't be helpful in case of parallel migrations.
