Not much, if anything. We are not upgrading the DSpace software itself, and no new DSpace features will be included. You may notice improvements in performance (faster loading time, for instance) because of the improved operating system, database software and web server software.
If you are interested in the details, here’s what is changing with the software systems underlying and working with DSpace:
Upgrading PostgreSQL from version 9.6 to 13

Upgrading Shibboleth from version 2.6 to 3.3
Moving from Amazon Linux 1 to Amazon Linux 2 operating system
What will happen during the migration?
