Post replication system shutdown

So I built a new Truenas going from an Intel Core i7-6700K to an Intel Core i9-12900K. So I replicated my main data set. Everything went smooth. Now this truenas has shutdown for no apparent reason and so has the other one. I was having issues with the other one that I couldn’t pinpoint so that was an additional reason to build a new one. I am really stumped. I have tried over and over to pinpoint what made the other one shutdown once every day or so and could never figure that out. Both stayed up for 4 days during the replication and now less than 7 hours after completing. The new system has no apps installed and I haven’t copied over the configuration yet. Wanted to get all the data moved. Only thing it has is cloud syncs which occur at midnight and they ran successfully as I checked when the replication was completed. So I am at a miss. It wouldn’t make sense to me, why replicating data would bring over any errors. Anyone have experience with anything like this? Would love to hear your experiences or suggestions.

Thanks.
