It is official, we are sunsetting Pangea.  While this phasing out will take some careful consideration and migration, we wanted to make sure to document up front what we believe will be the process.

Why are we doing this?

Pangea has been our go-to collaboration tool since 2006.  It has gone through many iterations in terms of access, storage capacity and host hardware/software.  At one point we even had two of them!  However, in today’s world Pangea has been forced to compete with enormous pools of cloud based storage and it is now clear it cannot keep up in a fiscally responsible way.  One good example of this competition is the free OneDrive space we all have access to as part of our campus O365 contract.  Pangea allots a default 20GB for personal shares, while OneDrive serves up a whopping 5TB (roughly 250 times more space).  Also, OneDrive is available at zero additional cost.  By migrating most of our Pangea shares to these other more modern scenarios, we can easily save close to $2,500 annually just on primary storage charges.  Beyond the financial motivations behind this sunsetting, there is also some clear technological advantages to migrating to other collaboration tools, which are outlined here: https://wp.natsci.colostate.edu/cnsit/collaboration-and-file-sharing-tools

How are we going to do this?

We can consider Pangea data as 3 different types.  There is personal Pangea space, collaborative group space, and finally Pangea served web space.  We will address these all separately in turn.

Stage One – Personal Pangea Space Migration

Our first goal is to migrate all personal Pangea spaces over to OneDrive.  We have created a writeup for this here and are ready to assist with user migrations immediately. https://wp.natsci.colostate.edu/cnsit/converting-a-personal-pangea-space-to-onedrive

Stage Two – Collaborative Pangea Group Space Migration

For stage two, we will be transferring all collaborative groups from the Pangea VM over to the new ACNS hosted RStor service.  Collaborative Pangea groups include lab groups (eg: “peersenlab” and “medfordlab”) and other special project groups (eg: “x-ray_facility” and “traits_model”).   As this RStor space will be paid for departmentally, Pangea-era quotas will remain in effect as they are at migration.  If additional space is required for these groups, an official, group funded RStor arrangement must be made.  For example, if you suddenly realize your lab needs more than the 100GB quota they have been using with Pangea, RStor space can be purchased in blocks of 1TB at $70 per year.  The challenge for this stage is simply that users will have to remap their groups at its new location.  We have plenty of documentation on this here: https://wp.natsci.colostate.edu/cnsit/rstor-how-to

Other collaborative groups, such as staff, accounting, departmental, and advising shares will be migrated over to the O365 SharePoint Online sites model.  These migrations will also involve close cooperation with the share’s user group and CNSIT.

Stage Three – Pangea Web Group Migration

The final migration involves Pangea served web groups.  These need to be addressed individually to find out where the best new home might be.
