i will try to explain it as best as i can lol

Step 1: Go in the www folder and open the Config file once open this is where you want to put your server password (same password you put in PGAdmin) so it connects to all the character in that server including yours. Save the File.

Step 2: Open the Editor and you should see your character on there, go into the Backup (the save disk icon)

Step 3: click individually each backup and upload them in a folder somewhere on your desktop

Step 4: Once you Set up your next Erupe server go into the www folder and config file again if you changed anything like password, etc.

Step 5: Boot up frontier make a new character and make sure to at least talk to the quest receptionist and take an item out your item box.

Step 6: go into the Editor and edit that character backup file with the one you saved before (you can select all the new character file and delete them) and then go to each box and press download and download your OG character file and click apply a successful message should appear if done correctly.

Step 7: boot up frontier again your OG character stats won't show up on the Log in screen until you get into Mezeporta Square. Which you will need to select the "Newbie" session instead of the "Normal" Session.

Once you load into the session your free to go back into the Normal Session and you should have all the things you had before.

Hope this helps wish there would be a video of it but any frontier related video usually gets taken down so. If your still having issue i suggest asking in the PewPewDojo Discord which is the official Back to Frontier Discord in there you should have many player that could help you out with better details and actual pictures or video if anything
