This feature is only compatible with Legacy NFTs (Standard or Programmable NFTs)
The Create Migration Collection utility allows you to create a new collection NFT and add existing legacy NFTs to it. The primary use case for this tool is if you have existing legacy NFTs that either don't belong to a collection already or you would like to regroup them into a new collection.
Go to the Utilities page and click on "Create Migration Collection".
Enter the image, name, and description that will represent the collection in wallets and marketplaces.
Click Create then sign the transactions that come into your wallet extension. Once complete, click Add Existing NFTs to Collection to proceed to the next step.
You have three options to upload your legacy NFTs to this new collection:
Individual NFTs - If you do not have many NFTs you can simply copy each address into the box that says "Enter a NFT address" and click Add to open an input field for the next NFT.
Verified Creator - If you don't have a mint list handy, or if the collection predated the Metaplex Certified Collection standard, then you can also add NFTs based on the 1st Verified Creator which is typically the Candy Machine itself. To find this address you can look at the "creators" array in the metadata of an NFT and find the 1st creator address where "verified" = 1.
CSV File - If you have already have a mint list, or have generated a hashlist from our Generate Hashlist utility, you can upload this CSV to assign legacy NFTs to your new collection.
Once you have uploaded the NFTs (either through addresses or 1st Verified Creator) you can click Add to Collection in the bottom right corner to complete the action. Please make sure to approve all transactions that come in on your wallet extension.
