Hi Danny, Thanks for your quick response. I’m thinking of approach #2, but I’ll discuss this with our developers first and see if they have a preference.

There are sort of 2 paths I can think of for you to choose from here. 1) On your new system, start with 4.x and recreate your old system first, including all of the configuration and security database setup, and then upgrade. If by 4.x you mean 4.2, the upgrade would be 4.2 -> 4.2.latest -> 5.0.latest -> 8.0.3 (or latest at the time). If you do this, I would recommend turning reindexing off in your content database(s) before moving from 4.x, and then enabling it when you are running 8. or 2) Recreating your configuration on the new 8.0 machine (all of your databases, app servers, forests, users, custom roles, custom privileges, and so on). Then restore your databases to the new system, then reindex. The advantage of doing 1) is that it is easier to recreate your configuration. The advantage of 2) is that is it less upgrade steps (not that the upgrade steps are hard, they are not hard). If your system is relatively simple, I would try 2) and see how that goes. Is this a cluster or a single node? If it is a cluster, you will need to recreate the host configurations as well. -Danny From: [email protected]<mailto:[email protected]> [mailto:[email protected]] On Behalf Of Fred Seaton Sent: Thursday, June 18, 2015 3:00 PM To: MarkLogic Developer Discussion Subject: [MarkLogic Dev General] Migrating from ML 4.x to ML 8 Hi, We’re in the process of migrating from MarkLogic 4.x to 8.x. We’re not interested in doing it in place, so I’m setting up a new server with 8.x and am planning to migrate the databases from the old server to the new. Is there a documented set of procedures for doing this? I’ve read about backup and restore, as well as the incompatibilities between the versions, but not much more. Can anyone give me some guidance? Thanks. -- Fred Seaton UNIX System Admin Digital Library Development Center, University of Chicago Library _______________________________________________ General mailing list [email protected]<mailto:[email protected]> Manage your subscription at: http://developer.marklogic.com/mailman/listinfo/general
