how would i fix this

[storm vapor]

so i made a mistake when making a kills script. i made it so it saves variables to the player's username not uuid so when they change their name there kills get wiped. i know how i can change the skript to saving uuid but wouldn't that wipe every player's kills? anybody have any ways to transfer all of them. this is for a server with hundreds of members with most having hundreds of kills. thanks

    {kill counter.%player%.kills_total} = 0

on death of player:
    attacker is a player
    if attacker is victim:
        stop
    add 1 to {kill counter.%attacker%.kills_total}
    
command /kills:
    executable by: players
    trigger:
        message "You have %{kill counter.%player%.kills_total}% kills in total."
        
command /getkills [<offline player>]:
    permission: skript.getkills
    permission message: you dont have permission
    trigger:
        send "The player &b%arg-1% has &6%{kill counter.%arg-1%.kills_total}%&r kills in total." to  player
        
command /minuskills [<offline player>] <number>:
    permission: skript.minuskills
    permission message: you dont have permission
    trigger:
        subtract arg-2 from {kill counter.%arg-1%.kills_total}
        send "The player &b%arg-1%&r now has &6%{kill counter.%arg-1%.kills_total}%&r kills total" to player
        
command /addkills [<offline player>] <number>:
    permission: skript.addkills
    permission message: you dont have permission
    trigger:
        add arg-2 to {kill counter.%arg-1%.kills_total}
        send "The player &b%arg-1%&r now has &6%{kill counter.%arg-1%.kills_total}%&r kills total" to player```

iirc there's a snippet that does it

but you should also use lists to make it easier :: not .

yeah you cant even migrate cause youre not using lists

your only option is to go into your csv, find and replace . with :: then use this
