$PI This is the most challenging upgrade in recent years, far from a simple tweak or fix, but a comprehensive overhaul and optimization of the entire underlying architecture.

This upgrade covers the synchronized update of three core components: the protocol version from 22 to 23, the server system upgraded from Ubuntu 20 to the more stable Ubuntu 24, and the core database updated from PostgreSQL 12 to 16.
In simple terms, it’s like replacing the entire system with a brand new "operating framework," "support platform," and "data warehouse."
The synchronized update of these three core systems presents the biggest challenge in adaptation and compatibility.
The new and old systems, new and old data need to be integrated and aligned one by one, and a vast amount of historical data must be reorganized, categorized, and adapted to new rules.
The whole process is like renovating and reinstalling a large shopping mall that is still in normal operation—updating all facilities without affecting the mall’s normal operation, requiring extremely high levels of effort and precision.
