## Symptoms

- * "`There are no log servers available`" error in SmartConsole after transferring the $RTDIR/log_indexes content from one server to another.

* The *$RTDIR/log/solr.log* file on the Management Server contains these errors:

  `
  Caused by: org.apache.lucene.index.IndexFormatTooOldException: Format version is not supported (resource BufferedChecksumIndexInput(MMapIndexInput(path="/var/log/opt/CPrt-R81/log_indexes/template/data/index/segments_1"))): 0 (needs to be between 6 and 9). This version of Lucene only supports indexes created with release 6.0 and later.`

  `  

  `
  ERROR [qtp-2054820151-9905] org.apache.solr.servlet.HttpSolrCall.log:159 - null:org.apache.solr.core.SolrCoreInitializationException: SolrCore 'template' is not available due to init failure: Error opening new searcher`  
  `
  at org.apache....
  `

## Cause

The format version of the *$RTDIR/log_indexes/template/data/index/segments_1* file does not match the version of SOLR on the server. This usually happens when files are moved from a server with one SOLR version to another server with a different SOLR version.
