Smart contracts won't have the same address on L2 after migration, that it why you introduce L2ContractMigrationFacet.sol. Via this Facet owners of smart contracts can migrate Internal Balances and Silo deposits to any receiver they specify.
However there is missing logic for Fertilizer ERC1155 migration. There is only ReseedBarn.sol which mints Fertilizer to account, but it's similar to ReseedInternalBalances.sol - Fertilizer can be minted only to EOA owners, because address of smart contract on L2 is not known in advance.
Smart contract which own Fertilizer will lose it after migration to L2
