Are you changing just the host OS or the JVM, or both, from 32 bit to 64 bit?
If it is just the OS, the answer is definitely no, you don't need to do anything more than copy. If the answer is the JVM, I *think* the answer is still no, but others more authoritative than I may wish to respond. -----Original Message----- From: - - [mailto:loh....@hotmail.com] Sent: Thursday, September 29, 2011 5:15 AM To: solr-user@lucene.apache.org Subject: 32-bit to 64-bit Hi, I indexed my data on my 32-bit computer.Do I need to re-index if I upload my data to a 64-bit server or does copying the data directories would suffice? Thank you.
