Can Solr v1.4 and v4.0 co-exist in Tomcat?
I have an existing v1.4 implementation of Solr that supports 2 lines of
business. For a third line of business the need to do Geo searching requires
using Solr 4.0. I'd like to minimize the impact to the existing lines of
business (let them upgrade at their own pace), however I want to share
hardware if possible.
Can I have Solr 4.0 and Solr 1.4 co-exist in the same Tomcat instance? If
so, are there any potential side-effects to the existing Solr implementation
I should be aware of?
Thanks,
Ken

Thanks, that helped with a different issue I was having. However the Admin UI
issue is a known issue with IE9 (and possibly IE8)
https://issues.apache.org/jira/browse/SOLR-3876
https://issues.apache.org/jira/browse/SOLR-3841
basically IE is not supported for the Solr Admin UI at this time. I
installed Chrome on the Development server I'm working with and everything
worked just fine.

Our setup generally follows these instructions:
http://wiki.apache.org/solr/SolrTomcat#Multiple_Solr_Webapps
BTW, we're running on Tomcat 6. You'll definitely want to undo your changes to the Tomcat lib directory since you don't want anything Solr-related shared across your web apps.

I renamed the 4.0 .war file solr4.war and put it in the \lib directory of
Tomcat (where solr.war already exists for version 1.4.1). I have a new core
created using the solr example that came with 4.0. It looks like I can run
queries and do a few other things using the URL, but the Solr Admin UI
doesn't work. The screen comes up but clicking Dashboard or Core Admin etc
do nothing. They just change the URL to /solr4/#/~core or something like
that. I get the feeling the hashtag should be something else but I can't
figure out how to get it to work. The old Admin tool works fine for both my
1.4 cores.
Have you gotten the new admin UI to work successfully? Do you remember what
you did to get it to work?
Thanks,
Ken

Hi Ken-
We've been running 1.3 and 4.0 as separate web apps within the same Tomcat instance for the last 3 weeks with no issues. The only challenge for us was refactoring our app client code to use SolrJ 4.0 to access both the the 1.3 and 4.0 backends. The calls to the 1.3 backend use the XML response format while the 4.0 backend use the Java binary format.
