Thanks Alex for the quick response! " First of all let me tell you that I am very new to JCR and might have very basic questions in mind. Also the repository which I have to migrate has been created using Liferay Portals, where the meta data for repository is being stored in the application database and the content is being stored on file system, which i have to migrate to a db now.
I am migrating it using repositorycopier.java in a stand alone java program." Now, when I am trying to compare the two repositories using JCR API, i m not able to do so. I am able to login to the repository, but it does not fetch me further values .i.e nodes and properties :(... these values are null.So at times i doubt whether i am actually getting logged in to the repository or not :( . There is a file in my repository named 'repo.properties' and has the values like : jcr.specification.version=1.0 jcr.repository.stats.nodes.count=179962 query.xpath.pos.index=true jcr.repository.version=1.6.0 query.xpath.doc.order=false jcr.repository.stats.properties.count=831457 (There are some more properties also, but i have copied a few of them here.) I hope these nodes.count and properties.count are the actual node and properties count of my repository. Please confirm. After migration to DB, I am able to see these properties in one of the tables, but there the nodes.count and properties.count values are zero :(. If somehow I could know that where does the 'MySqlPersistenceManager' stores these values, and if these values match, would that confirm that all the documents along with their version have been migrated?

First of all, most persistence managers have a consistency check option that you should run first, because it's probably the fastest: http://wiki.gxdeveloperweb.com/confluence/display/GXDEV/How+to+repair+a+'corrupt'+JCR Then, to compare the actual data with the original copy, iterate over the two repositories and compare the nodes and properties. You would probably run one repository as transient and the other remotely, using davex, to reduce delays as much as possible. If it is only about (nt:)files, you could also mount both as webdav and have a shell script that does that iteration and uses some (binary) diff tool to compare the data.
