- While upgrade from 5.3 to 5.5, please do not replace complete newly installed
conf/directory with backup
- While upgrade from 5.3 to 5.5, only few files need to be replaced namely
metadataspec.xml, preview-server.xml, server.xml
- The files that were modified during 5.3 (for example,
wrapper.conf) must be merged with the corresponding file from the newly installed
- The remaining files from the newly installed conf/ directory must be retained.
