3. Based on the type of the plan that you have had the standalone app in right before adding it in Zoho One, you may fall into any one of the following cases:
   
1. Case 1: If it was that advanced plan (Ultimate plan with CRM & Staffing version with Recruit), which is only offered as an add-on within Zoho One: An alert note will appear saying that you had this advanced plan subscribed for the standalone instance of the app you were using earlier. It goes on to ask if you want to proceed with the same plan in Zoho One as well. To enable it, click Add.
   
2. Case 2: If was any other standalone plan: You will be set to the default plan offered in Zoho One. To enable the add-on plan either during the addition of the app to your Zoho One organization, or sometime later, you need to write an email to support@zohoone.com.
