Can't sync historical data from older chains #697

Closed HussienAbdelaal closed 2 years ago

HussienAbdelaal commented 2 years ago

Describe the bug I'm working on an enterprise version blockchain explorer. I'm currently running an archival full node and its successfully syncing with Columbus-5 network. However, I'm unable to sync with the previous networks (Columbus 1,2,3 or 4) to fetch their data: the first 4,724,000 blocks

To Reproduce I followed the steps mentioned in Columbus-4 upgrade instructions trying to sync with Columbus-4 network but it got stuck at INF starting ABCI with Tendermint for a long time (about 24 hours). so couldn't get it to start.

Context & versions I'm using an ubuntu 20 instance which successfully runs Columbus-5 network with core version 0.5.17 When trying to run Columbus-4 network I used the same ubuntu instance with core version 0.4.6

(if applicable) suggested solution

I'm interested in the same issue, which is how can I get the data for the first 4,724,000 blocks from the network itself?

To be synced, we need other full node which have whole block data.

How can one get other full node which have whole block data. The answer provided doesn't solve the issue. Is there any full node which have whole block data that's avaialble to get snapshot from, like on AWS or other cloud storage, or maybe even through some scp?
