AAs are set to activate at MCI 5,210,000 which is expected at the end of February. Since this is a protocol upgrade and therefore a breaking change, all nodes, including light nodes, need to upgrade.

For full nodes, the upgrade will take a very long time since the update also includes moving part of the data from SQLite database to a much faster RocksDB database. The conversion of data will be done when you launch the wallet for the first time after the upgrade and it will take several hours (in our experience, from 3 hours on a dedicated server to 39 hours on a VPS), so please plan accordingly. RocksDB database will take additional 15 GB of disk space, please check that you have enough free disk space before the upgrade. Create a backup before upgrading.

For light nodes, the upgrade will be much faster since their database is usually small, but light nodes with long transaction history can still experience a noticeable delay during the first start, especially mobile ones on older hardware.
