I'm trying to make an update from my dspace server to dspace 3.1. I followed all the step, and before the migration, i've copied all data to a new and cleaned dspace 3.1 server. The full application seems to be running right but when I go to oai-phm interface to list Records and Identifiers, the server asks "
No matches for the query"

http://my-server-ip:8080/oai/request?verb=ListSets --> Lists Sets perfectly
my-server-ip:8080/oai/request?verb=ListMetadataFormats --> List Metadata perfectly

my-server-ip:8080/oai/request?verb=ListRecords&metadataPrefix=oai_dc --> Return "No matches for the query"
my-server-ip:8080/oai/request?verb=ListIdentifiers&metadataPrefix=oai_dc--> Return "No matches for the query"

The logs file show no errors and i am sure that there are data inside.

Can you help me? Thank a lot
