Rehosting Solr is currently considered Out of Scope. The Windchill Rehosting Utility 2.0 will include the ability to rehost Solr, and the guide released with this utility will include the instructions.
Though, it is still possible to rehost Solr. All the Solr data is stored in your <Windchill>/solr directory. Copying this directory over to your target system will copy over all of the Solr data. Then, you should just need to update the solr related properties to point to target system. Make sure that the below properties reference the correct location for the target system:
- wt.solr.host
- wt.index.solr.webapp.home
- wt.index.solrURL
- wt.indexing.indexHost
Also, make sure the Solr webapp configuration files for apache are pointing to the correct hostname. These files would be the files beginning with app-Windchill-Solr in <Apache>/conf/extra.
