I have got 6 set of quorum servers, out of which 3 are unreachable. So, now 50% of the network is down and I am unable to bring them up. Now, I am planning to run the setup on new set of servers with old data.

My question is --> How can I export the chaindata from old servers to new servers? I need a detailed explanation on that.

Thank you in advance.

  • Bt if you add new servers as peers. They should automatically sync the block chain from the 3 nodes which are Up. – logeekal Apr 24 '19 at 14:10

I got an answer and I am able to retain the old server data.

This is how I did: 1) I went to a location(any one old server) where chaindata(in .ldb format) is stored. 2) I zipped the folder in tar.gz format. 3) Then, I uploaded the tar.gz file in all the new server. 4) So, before starting the geth process in new server, I went to same location where chaindata is stored, I unzipped the file 5) Started the geth process in all new servers 6) All the new servers got synced with the old data
