Is there an upgrade path to perform an upgrade of Alfresco Enterprise Network v2.1.0 (112) to the current Community Edition? I am currently running the instance on a Solaris 10 SPARC server using PostgreSQL 8.4 as the backend store. Thank you.
You aren't going to be able to upgrade in one jump. You are probably looking at 4 or so upgrades. To a 2.2, 3.4, 4.1 and 5.0. Upgrade paths are documented and you will also see in these forums the issues people have had and how they solved them.
Thank you for your prompt reply. One final question, if you'll permit me to use this open thread. If I decide to remain at the current version of Alfresco, are there any issues (configuration or otherwise) with upgrading to PostgreSQL 9.3.5 (e.g. bytea_output)? Thank you, again.
There will probably be some small issues. However I'd expect that if you stick roughly to the supported posgresql version when upgrading then they shouldn't be too difficult.
