1) If you haven't already brought it inside, do it slowly. First an enclosed porch, then a vestibule, then a cold room, then a warmer room. A few hours in each. You want the moisture in the air in the warmer environment to condense slower than it's evaporating, otherwise you have water inside the phone.
2) Make sure all your contacts on the Note 2 are Google contacts. (If not, show the Phone and Device contacts, move them to the SIM, then move them from the SIM to the Google account. Now make sure you have Contacts sync turned on and sync the contacts.
3) Back up all your apps and data (
Helium will do that). If you moved any apps to the SD card, move them back to the phone first. (They have to moved on th phone they're being used on and to the card they're being used from. You can't copy the card, and you can't back up the app and restore it if it's on the card.)
4) Back up your texts -
SMS Backup & Restore will do it.
5) Copy all the backup folders (Helium's is named carbon, the rest are evident) to your PC. Copy all your music, pictures, videos, etc. to the PC.
Activate the Edge, then do everything in reverse, to get everything back. (Syncing the contacts should happen pretty soon after you enter the Google account (not the gmail account - that's for email, not for the phone.) If you had apps backed up on the Note, some of them nay show up on the Edge. Helium will still restore their data. (I prefer using
App Backup & Restore to back up the apps themselves - first to keep the functions of apps and data separate, second because AB&R saves apps as apk files, which can be installed by just finding them and pressing them - you don't have to install AB&R first [although it's easier if you do - find it, press it and it's installed. Then you can install any or all of the backed up apps [from the Archived tab].)
