Manual Seeding of Exchange 2007 database & Log Files

I did a manual seeding of Exchange 2007 on a exchange CCR Cluster. The "last inspected log time" shows the time before the database was dismounted to copy. Hence there is a big queue of backlog log files to be copied to the passive server

What are the precautions to be taken with log files on the active and passive server before manually seeding database files ( Dismounting the active copy and copying the database.edb file to the passive server)? do we need to delete the logs from only the passive server or both the servers

Here is an article with step by step directions for reseeding manually

To use the Exchange Management Console to manually seed the passive node by copying an offline database file
Open the Exchange Management Console.
Expand Server Configuration, and then select Mailbox.
In the result pane, select the Mailbox server that contains the database that you want to dismount.
In the work pane, right-click the database to be dismounted, and then select Dismount Database.
Suspend replication on the dismounted database. Follow the steps for suspending replication that are shown in How to Halt Replication for a Passive Copy in a CCR Environment.
After the replication is suspended on the database, copy the database file (.edb file) from the production database folder to the CCR database folder.

The location of the production database folder can be found on either the Summary page or the Properties page.  

After the database file has been copied from the production database folder to the CCR database folder, right-click the dismounted database, and then select Mount Database.

Seeding is complete when the file is copied. Client access is restored after the production database has been mounted.  

Resume replication for the dismounted CCR database. Follow the steps for resuming replication in the topic How to Restart Replication for a Passive Copy in a CCR Environment.

When manually reseeding I also delete the log files on the passive node before remounting the database on the active node.

When you dismounted the database on the active node the log files were committed so go ahead and run a full backup on your active node to remove the committed logs. Once you have cleared the committed logs restart replication.

My question was basically "what to do with log files" during a manaul seeding operation. The "Note" in the solution answered my query. However i failed to understand, after manually seeding why the pervious logs ( i mean logs before dismounting the database) were replayed?

sorry, the solution was in the second part and not in "note"  part of the solution
