What is a proper way to migrate the rrd4j.persist file ?

Strategies {
        everyMinute : "0 * * * * ?"
        default = everyChange
}

Items {
        Whirlpool_Bad_Feuchtesensor : strategy = everyUpdate
        Temp_OG_Wohnbereich : strategy = everyUpdate, everyMinute
        Temp_OG_Wohnbereich_KNX : strategy = everyUpdate, everyMinute
        Temp_Aussen_Nord : strategy = everyUpdate, everyMinute
}

Delete default = everyChange.

Given the rest of your setup that should be it.
