Exchange Mailbox moves and transaction logs

So I have a DAG and the databases are replicated.

If I move a 5 GB mailbox from Database01 to Database2, what should I expect to find with the transaction logs?

Should I see the log files grow by 5 GB in Database02 Log directory?

I kinda expect the logs to grow for the target, but not the source. But I am also seeing my source database logs grow.

Thanks!

I saw that technote, seems to apply to Exchange 2013 and 2016.
I am using Exchange 2010 to Exchange 2010 moves.

I don't really agree yes logs will be created at both the source and destination but the source shouldn't be nearly as big as the destination. The source mailbox register only the deletion which are small

this can be found documented in
https://technet.microsoft.com/en-us/library/ee832796(v=exchg.141).aspx#move

Although the source server logs the record deletions, which are small, the target server must write all transferred data first to transaction logs.

and
https://blogs.technet.microsoft.com/exchange/2011/11/09/capacity-planning-yes-transaction-log-space-is-critical-to-keeping-your-databases-healthy-and-mounted/

Mailbox moves also generate transaction logs.  Each mailbox moved to the destination database generates roughly enough logs (at the destination, not the source) that equal the size of the mailbox (including the contents in the Recoverable Items folders).

so while logs are expected to be found on both sides they shouldn't be at the same rate
