The need to update Ethereum clients arises as the Bellatrix update is configured to allow Beacon Chain to handle transactions.
According to data from Ethernodes, 73.5% of Ethereum nodes are now marked “Ready to Merge” ahead of the upcoming Bellatrix update for Ethereum on Tuesday.
The Bellatrix upgrade is seen as one of the last necessary steps before the official merger, which will see Ethereum transition to a Proof-of-Stake (PoS) consensus mechanism between September 10 and 20.
According to the Ethereum Foundation, to be ready for merging, Ethereum node operators need to upgrade Bellatrix by updating their consensus-level clients on the Beacon Chain to the epoch 144896 scheduled for 11:34:47 UTC on September 6, 2022.

However, with 26.5% of nodes marked “Not Ready” for an Ethereum merger, Ethereum co-founder Vitalik Buterin and main developer Tim Beiko took to Twitter to remind the remaining node operators to update their clients.
According to the Ethereum Foundation, node operators who are unable to hard fork Bellatrix will force their Ethereum clients to “sync with the pre-fork blockchain”, warning:
“[Node operators] will be stuck on an incompatible chain under the old rules and will not be able to send ether or transact on the Ethereum network after the merger.”
According to Ethernodes, most “off-the-shelf” nodes are on a Geth client that has not yet been updated to Geth v1.10.23 or higher.
Other Ethereum clients with node operators that require upgrades include Erigon, Besu, and Nethermind.
Ethereum nodes are required to validate blocks and can be run with various Ethereum client software depending on the programming language and codebase used.
After the Bellatrix update, the final part of the Ethereum consolidation will take place at the Paris event, which will be triggered when the total terminal difficulty (TTD) reaches 5875000000000000000000000, which is predicted to happen around September 15th.

When the execution level exceeds this TTD, the next block will be generated by the Beacon Chain validator. Completion of this block will mark the full transition of the Ethereum blockchain to a proof-of-stake mechanism.
According to the Ethereum Foundation, Ethereum users do not need to do anything with their Ethereum.
