Migrate Exchange 2007 to Exchange 2016/2019 without any paid tools

[Wiehan]

As my understanding there no direct path to migrate Exchange 2007 to the newer version Exchange 2016/2019 without any paid tools. So we need to move all mailboxes to Exchange 2013 (all exchange roles on the same box) then another move to Exchange 2016/2019 (all exchange roles on the same box).
This Exchange 2007 (CCR+SCR to DR) is using Windows 2003 with Microsoft NLB and I know both already EOL, but we still need to migrate them to Exchange 2016/2019 on-premise.
Since the customer only has limited hardware, we will use half of the server that becomes Exchange 2016 as an interim solution to host Exchange 2013 and we need to replace Windows NLB with the hardware load balancer. My question: do you foresee any issue if we still not touch Windows NLB at Exchange 2007 and use the new hardware load balancer on Exchange 2013?
So my plan is to move all mailboxes+public folder to Exchange 2013 and take over the Windows NLB IP to the new hardware load balancer when we decommission the Exchange 2007.
