I’ve a need to upgrade a single EV 12.5 server to the latest version (14.3) and was keen to understand any gotchas around the changes to the indexing engine (elasticsearch). I also need to migrate to a new Windows 2019 platform (from Windows 2012) so was planning to use SSMW. I can only see an SSMW for 14.2 so will use this version and then do an in-place upgrade to 14.3
Can anyone can offer their experiences when upgrading to 14.2 or later - especially when working with the new elasticsearch indexing engine?
I read that the compute resources for the EV server will need to be increased to 32GB RAM and 16 x vCPUs to cope with the elasticsearch and I need to create a new volume for the an elastic search index snapshot location.
What are the post-upgrade activities I need to complete with elasticsearch as this wasn't clear in the upgrade guide. How and when do I configure the index snapshot location (is this after or during the upgrade) and how and when do I configure the index snapshot backups?
Also - Is there a method to upgrade the existing non-elastic indexes to elasticsearch indexes and is it worth doing this?
many thanks in advance
