New items not visible in Archive Explorer after upgrade from Vault v9.0.2 to v10.0.2

Hi,

I'm validating EV (for Exchange) v10.0.2 In our DEV environment.

First, I've migrated (Vm) EV v9.0.2 (on W2K3) to (Vm) W2K8 R2 and then upgraded to v10.0.2 without issue.

Note: ESX server is v4.0 Enterprise Plus (not supported by EV v10.x) and MEM of Vm W2K8 R2 has 4GB (instead of 8GB recommended by Symantec)

Since that, new archives are not updated/visible in Archive explorer. Synchronization of indexes (64-bit) didn't update view in archive explorer and verification via EV console is Ok.

From Archive explorer, I receive this message "The archive that you are searching is being updated".

An idea how to resolve this issue?
