title: crm 2011 making changes to a managed solution entity
body: <p>we are currently working on a specific CRM development. As part of this development we are working with a different supplier who have provided us with a 'core' managed solution, a toolkit of sorts. This toolkit contains a number of entities/web resources etc but crucially contains the case and contact (renamed to customer) entities. As part of our development we need to extend these entities by adding attributes/amending form layout etc for both these entities.
  should i create a new unmanaged solution - select add existing - choose the customer entity.
  I can then make my changes (new attributes, form layout changes etc)
  I then publish my unmanaged solution as a managed solution to import into a UAT/Prod environment.
  Would this approach work ok?</p>
  
  <p>What if the supplier make changes to their core entity and provide us with an updated release? what happens then or what should i do?
  There are a couple of attributes (title and ethnicity) that are part of their entity but i need to work of global option sets so i have create 2 new attributes and these are displayed on the form in place of their's. I have not removed theirs but could this cause issues?</p>
  
  <p>any help appreciated
