Before you begin with GCCIN

Google Calendar Connector for IBM Notes

To use Google Calendar Connector for IBM® Notes® (GCCIN), you must meet the following requirements.

System requirements

  • A G Suite or G Suite for Education account.
  • IBM® Domino® server 6.5 or later for Microsoft® Windows® (32 or 64 bit).
  • GCCIN must be installed on a Microsoft Windows 2008 server or later.
  • A single Notes client with Domino Administrator installed.
  • The connector server ID must have editor (with delete rights) or above access to all mail files.
  • Administrator access to your Domino mail servers.

    Note: You might not meet this requirement if you're using a hosted mail server.

  • Microsoft Core XML Services 6.0.
  • The server responsible for polling Google servers must have access to the internet.

Notes requirements

  • You must retain the Notes mail files for each user who moves to Google Calendar. 
  • Each user’s Person document must be kept in the Domino directory.
  • Users must be identifiable as Notes mail users. If you set forwarding addresses, Domino won't return schedule information for these users. If you need to apply a forwarding rule, apply it at the mail file level for each of your users. The rule makes sure that Domino continues to respond to availability requests.

Important: Avoid data loss

Once a user migrates to G Suite, GCCIN wipes the existing Notes calendar and overwrites it with future Google Calendar events. To avoid losing data:

  • If you want to retain the Notes calendar, don't set a user’s Calendar field value to Google. 
  • Until the user is completely migrated to G Suite and no longer using the Notes calendar, don't set their Calendar field to Google.
  • If you're in a G Suite trial, don’t use GCCIN. Use GCCIN when you're fully committed to moving to a G Suite account.

In addition, GCCIN does not work with these tools: 

  • G Suite Migration for IBM Notes—If you’re migrating the same user at the same time.
  • Calendar Interop—Google Calendar supports only one external source of calendar availability data at a time.
