Bitcoin & Bitcoin-cash in Ubuntu same server : Use same Block Data for both Configured Bitcoin server/rpc working good in Digital Ocean Ubuntu VPS.
I also want to set Bitcoin-Cash server parallel in same server.

So do I require to download all blocks of bitcoin-cash node? because I already downloaded Bitcoin core blocks and BCC/BCC is forked from it. Your help could save my much BCC block sync time. 


  I'm aware of setting BCC server independently. Just wan to know can we
  use same downloaded blocks for BCC JSON-RPC?


Followed this link how to install bitcoin legacy and bitcoin cash on the same ubuntu server?
So do I require to download all blocks of bitcoin-cash node?
Yes. Bitcoin and Bitcoin Cash share a history, but only up to the fork.
Possibly you might be able to make yourself a bootstrap.dat up to the fork for Bitcoin Cash to load, depending on exactly what software you are running for each. There are accurate and working instructions for creating bootstrap.dat linked in another recent question here.
