Changing the repository indentifier breaks the entire repository index

Hi,

We moved the entire repository from one machine to another. Earlier the repository was managed by Archiva 1.2.1 with repository identifier as 'Identifier1'. Now we have moved to a different machine and so we copied the whole repository to the new machine and set up and configured new Archiva with the repository identifier as 'Identifier2' (different from what it was earlier). But pointing to the same old copied repository.

Here the problem:
Archiva is unable to search the artifact. And in the logs it says:

./logs/archiva.log:1585:2009-09-16 04:37:06,919 [btpool0-8] WARN org.apache.archiva.indexer.search.NexusRepositorySearch - Error accessing index of repository 'Identifier2' : The existing index is for repository [Identifier1] and not for repository [Identifier2]

Could you please help me know that is by default Archiva storing the index in the repository !! How can I fix this problem now?

Thanks in advance.
