RE: Solr upgrade question

[Margo Breäs | INDI]

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

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!

Solr upgrade question

[Margo Breäs | INDI]

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

Re: solr upgrade question

[Johannes Goll]

Hi Alexander,

I have posted same question a few month ago. The only solution that came up
was to regenerate the index files using the new  version. How did you do
this exactly with
luke 1.0.1 ? Would you mind sharing some of that magic ?

Best,
Johannes

Didn't get any responses.

But I tried luke 1.0.1 and it did the magic. I run optimization and after
that solr got up.

solr upgrade question

[Alexander Aristov]

People

Is were way to upgrade existsing index from solr 1.4 to solr 4(trunk). When
I configured solr 4 and launched it complained about incorrect lucence file
version (3 instead of old 2)

Are there any procedures to convert index?
