Thanks @konrad.sopala for quick reply
But, I was following the approach discussed in Transfer Ownership of tenant
I want to transfer all data including user, settings, application, rules etc. to my friend’s account. I am ready to remove that tenant from my account and transfer its ownership completely to my friend’s account.
My question is, if I use the approach discussed in Transferring ownership of a tenant, will there be any issues in the future (e.g. loss of user data/change in API keys/loss of applications)? Also, who will be responsible for the payment if the tenant’s ownership is transferred and I allow my friend to remove me from the tenant?
