Conversion of a sole proprietorship into private limited company

Hello sir

In Case of conversion of a proprietorship into private limited the takeover agreement needs to be executed after the incorporation of the company or before? and if agreement is executed after the incorporation then how do we allot shares to the shareholders at the time of incorporation? And if we mention in our MOA "to takeover the sole proprietorshio business" then do we have to submit any additional documents with ROC related to the sole proprietorship business? And what are the stamp duty charges and other charges or tax liability that needs to be incurred as a consequence of executing the takeover agreement? also when does the sole proprietoeship business needs to surrender its existing government registrations i.e. before executing the agreement or after? Can someone please list the chronological events that need to be done in this case?

Thanks in advance
