I tested the migration against the chopsticks_frontier_template_upgrade zombie test and these are the results.

Before the upgrade (using runtime 600):

No code stored for pallet-xcm precompile address (0x0000000000000000000000000000000000000804).

After the upgrade (using runtime 700):

Dummy code added successfully for address 0x0000000000000000000000000000000000000804.
