If you need to move the document bulk, you can either rsync the docs and repin them, or use IPFS native means of replication to remote -- haven't used those.
LibGen on IPFS used to work, try e.g. https://bafybeifaxsen4np54stc43phpnn3rh2crxie34d74yki43dultrh4vglqy/ -- but I have no idea about how much of the library corpus is pinned currently.
