Hi,
What is the upgrade path for Couchbase CE from 4 to 6? We are currently on 4.5.1 and looking to upgrade to 6.0.0. The upgrade matrix docs are not clear for CE, and more geared toward CE to EE. Based on those docs, however, it appears we need to go 4->5->6, but I just wanted to confirm.
Thanks!
Hi Jase,
Thanks for using our software. I have a question.
What is your current version of Couchbase Server? Is it 4.5.1 Community Edition?
Thanks for the reply Thuan. Yes, it is 4.5.1 Community Edition. We plan to stay on CE at this time.
Hi, yes, the preferred path is 4.x (CE)->5.x(CE)->6.x(CE). We do not officially support 4.x any more. So, this is the preferred path.
Hi Jase,
Here is an example of offline upgrade a cluster in centos 7.6 servers from your version 4.5.1 ==> 5.5.0 ==> 6.0.1
