Hi,I upgraded Alfresco 4.2.e to 5.0.b. After that there are many exceptions inside the solr.log.What I did:- Backup Database and alf_data (including the solr index)- Installations of 5.0.b- Testing the the new version- In alfresco-global.properties, set index.subsystem.name=solr- Roll in the Backup

I am experiencing similar issues with upgrading to 5.0.c. Did you solve this issue?

As moving from 4.x to 5.x changes the version of SOLR that is in use and probably changes the datamodel within Alfresco it would be advisable to delete your previous SOLR indexes and allow all new ones to be built. This may well take a while dependent upon the number of documents you have.

I have no direct experience but I would doubt SOLR 4 would react well to SOLR 1 indexes.

Hello,
Thanks for the suggestion regarding the indexes. Indeed I cleared the indexes when moving and recreated them with solr4.

There was still an issue in which documents which had the MLText metadata property would not be indexed. So far we have simply removed the MLText for now. This seems to allow the documents to be indexed and therefore searchable once again.

Thanks,
Andrew
