Address Leases not appeared in the scopes at DHCP Windows 2008 R2 ent

Question

Hi Friends,
Recently couple of days ago we have migrated from DHCP Server ( Windows Server 2003 R2 32 ) to Windows Server 2008 R2 64 bit Virtual Machine.
After migration, most of the scopes seem empty, no Address Leases appeared in the scopes even most of the reservations also not appeared from DHCP MMC but the client machines obtaining IPs and DHCP VM is working fine.
After investigation I have found following event log errors.
Are these event log errors related to this Issue and what will be problem. Please advise.

Delete ALL scope information from within the DHCP mmc
Type: netsh dhcp server import C:\dhcp.txt all in command prompt and press Enter
Right-click server name within DHCP mmc and choose refresh
