Solr upgrade question

Hi all,

At the moment we are working with Solr version 4.8.1 in combination with an older version of Intershop.
We have recently migrated our entire shop to a new party, and so there is room for improvements.

Are there any known issues with upgrading over that many versions in general, or with an Intershop version specifically?
If so we would appreciate your experiences/stories, so we can mitigate things beforehand.

Thanks in advance,

best regards,

Margo Breas | INDI

If you're going to migrate from that old a version of Solr, I think you 
will need to re-index completely and also check that all your queries 
work as you expect...there have been a lot of changes since then and 
don't underestimate the task!

Erick and Charlie, thanks for your responses. It's clear that it is better to read the CHANGES.txt files first and then decide in how many steps the upgrade should take place. 

Best, Margo

There are a _lot_ of changes since 4.8.1. 

1> plan on re-indexing the entire corpus. This is required when jumping more than one major version.

2> Treat it as a green-field application. In particular do not just copy your schema and config files into 8x and start running. Instead, identify any changes you made to 4.8.1 and make similar changes to the stock 8x configs.

3> Really read the CHANGES.txt files for both Lucene and Solr. It’ll be mind numbing, but you can get a good sense of the changes that affect upgrading by reading the “upgrade notes” for each release between 4.8.1 and the current version you settle on.

If the upgrade notes generate specific questions, don’t hesitate to ask.

Best,
Erick
