Help required, update process

[Dana 2]

Hello I hope someone can help me out with a few questions

I need to update Cura to v3

when I do this will I lose my custom material profiles? (it did last time I updated)

is there a process to stop this happening?

do I always have to plug in my Ultimaker 2+ to my Mac at the same time as the Cura update to update the printers firmware?

also I want to add my custom material profiles to my Ultimaker 2+

is there any way of importing from Cura without changing the MATERIAL.TXT file?

when I update firmware will I lose these profiles?

when I make a project in Cura what settings information is in the Code file on the SD card? because retraction and fan settings can be made in Cura but they are also in MATERIAL.TXT...

sorry if these are basic questions but I just do this as a hobby and I cannot spend multiple hours tinkering with the thing every time I want to make something or update software

I would also like to know how ofter is this software going to be updated as it seems 2.7 has only just come out and these frequent changes are a bit of a task if I have to change all of the above every time

many thanks of you do reply

Dan
