Discussion: Upgrade to KiloWhy or Why Not?

16

Questions

1. What key factors will motivate we to do upgrade? And how do Kilo meet our expectations?

- stability, security- performance, scalability- flexibility, manageability- interoperability- …

2. Which features we currently lack of, and has implemented in Kilo?

3. Which bugs we haven't fixed yet, but resolved in Kilo?

17

Questions

4. If upgrade, …- what challenges we have to overcome?- what impacts we have to deal with?- how much budget (time, human) we need?

5. If not upgrade, …- DIY everything!- waiting for a release more preferable than Kilo?
