[SalesForce] Transfer Account ownership without changing opportunity owner

Try this. It shuld help get started and uses all of the Standard SFDC functinaility without needing Triggers/APEX

Create Page > Create New Button (List Button: Source = VisualForce Page) > Edit Search Layouts for Accounts and Add this button to the List View

This screen allows you to transfer an account from one user to another. When you transfer ownership of an account, the new owner will also gain ownership of the following records related to the transferred account:

• all notes and open activities for this account owned by the current account owner
• all related notes and open activities owned by current account owner
• all opportunities within the account owned by current account owner, including all related notes and open activities owned by current account owner

Note that completed activities will not be transferred.

The new owner might need to edit sharing.

Maybe this will get you started :)

trigger setOwner on Opportunity (before Insert){

    Set<ID> acctIDs = New Set<ID>();
    Map<ID,ID> accToOwner = New Map<ID,ID>();

    for(Opportunity opp : trigger.new){

        acctIDs.add(opp.accountID);

    }

    for(Account a : [Select OwnerID From Account Where ID IN :acctIDs])
        accToOwner.put(a.id,a.ownerID);


    for(Opportunity opp : trigger.new){
        if(accToOwner.containsKey(opp.AccountID))
            opp.OwnerID = accToOwner.get(opp.AccountID);
    }


}
