CMs have been "training" for over a year now..
A very long time ago, they made posts in every land asking many to join the first "Test and Adjust" crew. This crew would consist of the first CMs working on the project. There were many classes people could attend that would give information on what to expect in the land and what the company expects from its CMs. Each CM would be assigned to one of the 2 specific attractions or "projects", however they are able to work both. These CMs for the most part work 12 hour shifts and work hand in hand with WDI to basically put together the attractions "Operating Guide" (An official book that teaches how to operate the attraction in every aspect). These CMs and WDI have been cycling vehicles and testing the attraction since April or May from what I know. These CMs would become the official Leads and Trainers of both attractions.... [This info exclusive to WDWMagic.com forums. Do not share on other platforms.]
Now, what's happening in February? Now they are accepting positions for their second round of transfers who will be the every day regular operators for opening season. Now that the Operating Guide has been written and constructed by WDI and the first round of transfers, these CMs will go through a regular training process similar to any other attraction at the resort.
Long story short, don't be worried thinking training will barely begin in February.... There have been tons of CMs already working in the land for months now alongside WDI. This is just a second wave.

I love sharing new information with fans just as excited as I am about this project, but for me to continue posting, I would appreciate it if we kept information on this website only. Thank you!***
