Subscription taken under a different ctid

Hi currently my subscription is taken under the ctid eg=ABC. All my ctrader accounts are also linked to the email thats associated with ctid=ABC, eg, abc@yahoo.com

I am considering putting all my ctrader accounts including my main ctrader that was used purely for subscription purposes back to eg CTID=DEF whereby the email = def@gmail.com

I separated my ctrader accounts for trading and subscription main account. For direct trading by me its not an issue as I can stop the trading till link is completed or ask that link gets changed on a public holiday eg 1/May/2021.

But what will happen to subs accounts created for subscription? The main account may not be able to relink to def@gmail.com as there were already subs account created for signals that i have subscribed (by "main" account i meant the ctrader account that will contain the funds needed for subscription). By subs accounts I meant the accounts created automatically by ctrader during a subscription.

In order to do this do i need to

a) stop the copying and remove the funds from subs accounts to main ctrader account

b) wait for broker support to relink this main ctrader account to def@gmail.com thats associated with ctid=def

c) resubscribed under ctid=def, whereby ctrader will again automatically create subs accounts

Please advise
