epirus-migration

This repository hosts migration scripts for the epirus blockchain explorer.

contract-registry-migration

The contract-registry-migration.sh is for migrating contract metadata files from one instance of epirus to another.

The steps for migration are as follows:

1. Ssh onto the epirus instance you want to migration from
2. Invoke the mongo shell with the mongo command - you may need to download the mongo client it with sudo apt install mongodb-clients
3. Run the following query in the mongo shell:

db.metadata.files.aggregate([{ "$group": { "_id": "$metadata" } }]).map(function(e) { return e._id })

4. Replace <CONTRACT_METADATAS> in contract-resigtry-migration.sh with the output of the previous command.
5. Replace <SERVER_URL> in contract-resigtry-migration.sh` with the server URL of the new instance of the explorer.
6. Run contract-resigtry-migration.sh

N.B. The script should be run on a machine that has access to the new instance of the explorer api.
