Compatibility test results for land_211f4bd8 ==> land_5359f060 (PR)
1. All instances running land_211f4bd8, generating some traffic on network
2. First full node land_211f4bd8 ==> land_5359f060, to validate new full node to old validator node traffic
3. First Validator node land_211f4bd8 ==> land_5359f060, to validate storage compatibility
4. First batch validators (14) land_211f4bd8 ==> land_5359f060, to test consensus and traffic between old full nodes and new validator node
5. First batch full nodes (14) land_211f4bd8 ==> land_5359f060
6. Second batch validators (15) land_211f4bd8 ==> land_5359f060, to upgrade rest of the validators
7. Second batch of full nodes (15) land_211f4bd8 ==> land_5359f060, to finish the network upgrade, time spent 876 secs
all up : 872 TPS, 5209 ms latency, 6150 ms p99 latency, no expired txns, time spent 250 secs
