schema.xml changes from Solr4 to Solr5

I'm migrating from Solr 4.6.0 to 5.4.0. We opted to use our old schema.xml instead of using the managed_schema because we have quite a few copyFields. Starting up solr server, we got this error:

Plugin init failure for [schema.xml] fieldType "text_general": Plugin init failure for [schema.xml] analyzer/filter: Error instantiating class: 'org.apache.lucene.analysis.core.StopFilterFactory'

On googling, we saw that StopFilterFactory is not deprecated yet. What could be the problem?

Also there's no comprehensive guide on how to use a schema from Solr4 in Solr5. Any suggestions?

Thanks

I am not sure if you have resolved your error.

There will be some major changes between Solr 4.6.0 and 5.4.0, and I think your error is due to the changes between the 2 different versions. It means your schema.xml is outdated and won't work for SOlr 5.4.0.

I suggest you doing the following:

When you install Solr 5.4.0 and create a new core, Solr will create a managed-schema file in the conf directory of the core directory. I suggest you compare managed-schema file to your old schema.xml file. For example, look for fieldType name="text_general" in your old schema.xml, and see the difference between the contents under fieldType name="text_general" and the contents under fieldType name="text_general" of managed-schema of Solr 5.4.0. One potential way to fix the error is by removing enablePositionIncrements="true" as Neeraj suggested above.

After the fix for the contents under enablePositionIncrements="true", if Solr gives another error regarding your old schema.xml, look for the location of your error in schema.xml and compare it to managed-schema as done above.

Don't forget to remove or move managed-schema file out of the conf directory since the managed-schema probably won't be something you want to use. You would want to use your old schema.xml, right?

Hope this helps.

Not sure about Solr 5.X.X but solved above issue in Solr 6.1.0 by removing enablePositionIncrements="true" from schema xml.
Solr may throw another error

Plugin init failure for [schema.xml] fieldType "edge_ngram": Plugin init failure for [schema.xml] analyzer/filter: Error instantiating class:'org.apache.lucene.analysis.ngram.EdgeNGramFilterFactory'

Removing side="front" from schema file will remove this error as well.
