Question

So I installed RavendDB on a Win2003 server using these instructions:

http://old.ravendb.net/documentation/docs-deployment-iis

And i get the following error when I try to browse to the site. Any ideas?

Version of log file is not compatible with Jet version

Answer 1

The RavenDB datastore uses Esent under the hood. As a result it’s not portable across OS versions. I.e. if you create a store on one version of an OS, it won’t necessarily work on another just by copying the files across.

You can use the RavenDB smuggler tool to import/export the data. Or do it manually.
