## Issue Report
### Environment
- **Ubuntu Server 22.04.4 LTS**
- **Advanced CLI**
### Problem
After migrating the system to a new disk I get the following errors after starting the domain node, without it everything works normally. Prior to the migration, the domain node worked without errors.
```auto

Hey, sorry for missing this! Which release was the node running before the migration?

Before the migration was this same release `gemini-3h-2024-jul-29`
, now already using `gemini-3h-2024-sep-03`

Did you see any log containing “Submit fraud proof” before the migration?
Your domain node seems deviated from the domain chain because it derives a different domain block from the consensus block, you check the hash of the domain block in the log and compare it with the block hash from [the auto-id domain RPC node](https://polkadot.js.org/apps/?rpc=wss%3A%2F%2Fautoid-0.gemini-3h.subspace.network%2Fws#/explorer).
We did observe a similar issue in one of our internal nodes, the root cause is the `mar-25` contains a breaking change and we didn’t upgrade from the `mar-22` release to `mar-25` in time, so some domain blocks were produced with the old release so result in a different hash. The solution is to wipe the node and resync from genesis.

After erasing the node and synchronizing it, I get the following logs:

How can I fix this error and what does it mean?

I noticed this with an Auto ID domain operator I was running. I discussed it internally with the engineers and it’s due to domain blocks being pruned. The fix is to add these flags to the domain side of your arguments (after the `--` ):
```auto
--blocks-pruning archive-canonical
--state-pruning archive-canonical
```
Unfortunately, this does mean you will need to re-sync from scratch which I did (took ~3 days) but I am now running an operator on the Auto ID domain without the `FetchAssignedMessages` errors.
