[jira] [Commented] (SOLR-15596) Ability for packages to be upgraded
over major versions
[ https://issues.apache.org/jira/browse/SOLR-15596?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17408928#comment-17408928 ]
Timothy Potter commented on SOLR-15596:
---------------------------------------
[~ichattopadhyaya] I'm not quite clear why an upgrade solution needs to be in 8x for this? Shouldn't 9.x solve the upgradability for packages from 8x? Typically with upgrade tools, it's the newer version that has to provide the upgrade path for older versions.

> URL: https://issues.apache.org/jira/browse/SOLR-15596
> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Components: Package Manager
> Reporter: Ishan Chattopadhyaya
> Priority: Blocker
> Fix For: 8.10

>
> In order to support cluster upgrades, we need a way for the users to upgrade their package versions easily.
>
> A solution to this is to let the users download multiple versions of a package into the system, and use the compatible one at the run time. The upgrade cycle will look like this:
> # User installs package {{mypackage}} with version {{1.0}} that is compatible with Solr 8x only.
> # User wants to upgrade his cluster to Solr9x.
> # User upgrades to 8.10 first (where this ticket should land).
> # User proactively downloads {{mypackage}} version {{2.0}} that is compatible with Solr 9x only.
> # Upon a cluster upgrade, when nodes come up, the nodes will load the latest version that is compatible, i.e. mypackage 2.0.
