1. No, as explained in the plan management section:
At the beginning of the implementation of this new plan, it will not be possible to upgrade from an individual plan to the multiplayer plans, such as DUO or SQUAD.
Therefore, direct migration from an individual plan to the DUO or SQUAD plans will not be allowed.
The only change permitted will be within the individual plan itself, such as transitioning from a monthly plan to longer options like quarterly or annual. The same rule applies to the DUO and SQUAD plans, where changing the billing cycle (e.g., from monthly to quarterly or annual) is allowed.
