Promote / Remove the old Permission/Rank and get the new rank

[Dhavex]

Hello everyone! I am new to the script and have also scripted something. I've done a Rank system and somehow wanted a "/ promote <offlineplayer> & / demote <offline player>" and I did too, but I do not understand a thing: how can I promote someone if he has the rank for example Staff and I want to promote him to admin and the other rank should be removed automatically.

options:
    #PREFIX
    r: &7&l[&c&lRANG&7&l]
    #PROMOTES
    promote1: pex user %arg-1% group add Azubi
    promote2: pex user %arg-1% group add Supporter
    promote3: pex user %arg-1% group add Moderator
    promote4: pex user %arg-1% group add SrModerator
    promote5: pex user %arg-1% group add Admin
    #DEMOTES
    demote6: pex user %arg 1% group remove Admin
    demote5: pex user %arg 1% group remove SrModerator
    demote4: pex user %arg 1% group remove Moderator
    demote3: pex user %arg 1% group remove Supporter
    demote2: pex user %arg 1% group remove Azubi
    demote1: pex user %arg 1% group remove Spieler
    #REMOVE
    remove1: pex user %arg 1% group remove Spieler
    remove2: pex user %arg 1% group remove Azubi
    remove3: pex user %arg 1% group remove Supporter
    remove4: pex user %arg 1% group remove Moderator
    remove5: pex user %arg 1% group remove SrModerator
    remove6: pex user %arg 1% group remove Admin


command /promote <offlineplayer>:
    permission: rang.sk
    usage: {@r} &7Nutze: &e/promote &7<Name>
    executable by: player, console
    trigger:
        if arg 1 is not set:
            send "{@r} &7Nutze: &e/promote &7<Name>"
        if arg 1 is set:
            execute console command "{@promote1}"
            execute console command "{@remove1}"
            send "{@r} &7Du hast &a%arg 1% &7erfolgreich den Rang &aAzubi &7gegeben!"
            stop
        if player has permission "Azubi":
            execute console command "{@promote2}"
            execute console command "{@remove2}"
            send "{@r} &7Du hast &a%arg 1% &7erfolgreich den Rang &aSupporter &7gegeben!"
            stop

Just make two commands executing whenever you type the promote command. For example:

command /promote <player>:
    trigger:
        make console execute command "/pex user %arg-1% group set blabla"
        make console execute command "/pex user %arg-1% group remove blabla"
