Replacing SSD on Ally X, need help please

I have day one rog ally x, works amazingly well. i bought 980 pro with heatsink 2 tb a month ago but so far dont have the guts to upgrade.

I have few questions please:-

1- Did you feel lack of performance after the upgrade vs how it was stock?

2- Upon completion of cloud recovery of new drive, do i need to install AC and Asus app manually or they are just there like when we buy the Ally x?

3- Do i need to format the 2TB ssd before puttin in the ally or the cloud recovery process formats it and take cares of that part?

4- On scale of 1-10, how difficult was it to remove back cover, i have a nice kit from Temu which has guitar picks and correct size screw drivers.

5- I am worried about the battery clip, can i replace the SSD without taking off the battery clip?

6- Since there is a chance of static charge, will wearing Vinyl gloves elliminate this chance?

7- the SSD from. Ally x will be added as additional SSD to my rog laptop. Do I need to worry abt bit locker stuff or a simple format will make it work?
