Move Database and log path (DAG)

Hello,

I have 2 Exchange 2013 servers(EX01,EX02) in DAG cluster(10 databases).
3 disks for DBs and 3 disks for transaction logs.

One drive is running out of space and i need to move one of the databases named DB01 to another disk.

If I move Move-DatabasePath MDB02 -EdbFilePath E:\DB01\DB01.edb,database would be dismounted and offline.

Is it posible to create new database DB02 on E:\ drive, add a mailbox database copy for this database,move mailboxes to DB02 and delete DB01.This way database wouldn't be offline.
Only thing that I'm concerned is transaction logs generated during mailbox migration because I dont have alote of space on database disk but I have some space on logs disks.
https://support.microsoft.com/en-us/topic/large-transaction-logs-are-generated-when-you-move-mailboxes-in-exchange-server-2013-or-exchange-server-2016-administration-center-b0d99813-08f4-399d-5de7-15b53709ead7
Are those transaction logs genereted only in migrations from one server to another?Where they are generated?What size?Any advice?

Yes, you can do that. The most transaction logs are generated on the destination drive, so if you have room there, then you are good.
You could also enable circular logging on the databases and not generate logs at all.

I prefer your method versus dismounting, I never like to do that if possible.
