We have a great QE team and they test our updates to make sure they are safe. If you have concerns, before you start the upgrade take a VM/LVM snapshot, and also be sure to run "db2bak". We support replication between major releases normally (IE 1.2.x to 1.3.x OR 1.3.x to 1.4.x). This can be run for a while, but generally we don't advise more than a few months, as it's always better to keep your topology on the same versions. > > Also if I have a Replication server with a Master and read only slave, what is the procedure or best practice to update? > Thanks! It's really up to you. Having a plan, including backout strategy is always wise. If this was my environment I would probably make my plan something like: * backup (db2bak) read only replica (avoid use of the word slave these days :) ) * snapshot the read only replica (vm/lvm) if possible * perform the upgrade on the replica * run a sanity/acceptance test - do client applications still work, can you search for users, etc. * wait a few days Now do the same on the read-write server. The backout plan is: * If the acceptance test fails, revert the snapshot. You may need to perform a nsds5startreplicarefresh to reset the read-only replication information as this may cause a replication desync. * If the snapshot roll back fails in some way, destroy the host and rebuild a new ro/rw replica with the content from db2bak/dse.ldif etc. Hope that helps, > > Regards, > > -- > > Fernando Fuentes > Supervisor & Senior Systems Administrator > Email: ffuentes@xxxxxxxxxxx > American Alloy Steel, Inc. > Houston, Texas > Website: http://www.aasteel.com > Phone: 713-744-4222 > Fax: 713-300-5688 > _______________________________________________ > 389-users mailing list -- 389-users@xxxxxxxxxxxxxxxxxxxxxxx > To unsubscribe send an email to 389-users-leave@xxxxxxxxxxxxxxxxxxxxxxx > Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ > List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines > List Archives: https://lists.fedoraproject.org/archives/list/389-users@xxxxxxxxxxxxxxxxxxxxxxx — Sincerely, William Brown Senior Software Engineer, 389 Directory Server SUSE Labs _______________________________________________ 389-users mailing list -- 389-users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to 389-users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/389-users@xxxxxxxxxxxxxxxxxxxxxxx
