Method to self migrate from the old ScannerRegistry NFTs to a single ScannerPoolRegistry NFT, per chain. WARNING: ScannerNodeRegistry's manager addresses will not be migrated, please user ScannerPoolRegistry's methods to set them again.
| Name | Type | Description |
|---|---|---|
| scanners | address[] | array of scanner addresses to be migrated. All the scanners willing to migrate (optingOutOfMigration flags set to false) ScannerRegistry ERC721 identified by the uint256(address) in the input array will be: - Registered in ScannerPoolRegistry to the scannerPoolId either indicated or generated, with the same chainId and metadata. - Deleted in ScannerNodeRegistry. The ERC721 will be burned, disabled flags and managers deleted from storage. Scanners with optingOutOfMigration flags == true will be ignored (opted out), and will stay in ScannerNodeRegistry. At migration end, they will stop receiving work and rewards. |
| scannerPoolId | uint256 | If set as 0, a new ScannerPoolRegistry ERC721 will be minted to scannerPool, otherwise it must be set as a valid ScannerPoolRegistry ERC721 id owned by scannerPool. |
| chainId | uint256 |
| Name | Type | Description |
|---|---|---|
| [0] | uint256 | ScannerPoolRegistry ERC721 id the scanners are migrated to. |
