Help with rescan on a btc node

[bitcoinbrisbane]

I've had to resetup NBXplorer against a full node. However, I cant rescan to get old txs.

• Setup full node
• Setup Nbxplorer
• Run Nbxplorer
• Post to track the xpub key (OK returned)

Then try rescan:

./run.sh --chains=btc --btcrescan --btcstartheight=500000

Has the result

@bitcoinbrisbane try --btcrescan=1, that said, NBXplorer will probably be way too slow. imho you shouldn't rescan with it, and rather rescan utxout set (see the API) so you can restore the balance, utxos and make the rest working.

Thanks for the fast reply as always. --btcrescan=1 didnt seem to work. There have been hundreds for txs from this xpubkey too.

If the utxout rescan doesnt work, ill try migrate the old dbtrie

Update:

• On the old node with dbtrie I manged to install dotnet core 6
• Did a pull from main branch
• Ran ./build.sh
• Updated the ./run.sh file to have the Postres conn string

All seems fine, connects to the full node and postres. Now trying to import the old dbtrie following https://github.com/dgarage/NBXplorer/blob/master/docs/Postgres-Migration.md, but not seeing the balance. Seems to do it too quick.

./run.sh --automigrate=1

Update 2:

• Ive used the deprcated flag --dbtrie to get the node synced

This has allowed my to get the balances correctly. I'd still like to swap to Postgres as its a managed db, but cant seem to migrate.

Going to close this issue.
