It should not be necessary to do anything other than to make sure you have the proper shareholder accounts set up in the General Ledger in Equity section.  Set up your new bank account.   Did you get a new HST number?  

Thank you for replay and we have HST number belong the corporation number from long time ago and we never change the business number but we update the bank and all kind information in Ontario Business Registration ,,,, when you said set up the proper shareholder set up in General Ledger in Equity section it was my question to have these setup because if it`s not necessary to change the corporation set up to shareholders some hoe i have to set up the accounts in equity,,,have you any idea how to do it ,,,, please  THX
