Re-denomination of home currency following re-valuation

SUGGESTED

We have had a re denomination of our home currency - knocking off a few digits, probably  at a rate of 2,481 : 1 - yet to be confirmed.
How do we convert the several company accounts to operate with the new re-valued home currency?   Technically the Zimbabwe government has, on 5 April 2024, introduced a new home currency, replacing the RTGS dollar unit.
Do I open up a foreign currency account for the new currency (ZiG dollar) and then convert the home currency to the new one?  How is this done? 
Back in the 2010s there was a convert programme to knock of f zeros during out hyper-inflation… is that still current?
We further need to know the implications of any changes you recommend on the fiscalised device systems... I trust we will not need to bring is the support teams from the fiscalised device teams... they still haven't sorted out the QR code issue on some companies.
