WRF save files for future ndown run

Hello everyone,

I'm familiar with WRF model and run daily a two domain model using one-way nesting. I wanted to know which files should I save from this first 2-domain run in case in a future I want to run a d03 domain with ndown (using wrfout files from d02).
If I don't know the final domain (I can't create met_em files right now), what should I save from WPS?
If I knew the domain, could I just save wrfinput and wrfbdy files from real.exe with all three domains? Would I need met_em files?
Also, I wanted to know which met_em files are mandatory when running a ndown simulation. I read somewhere that for d02 domain end_date could be set as start_date, so just one met_em.d02* would be generated. Is it true? However, if in the future I want to run a d03 domain, should I also execute all met_em files for d02?
Sorry about the chaotic questions, I'm looking for an optimal way to get my idea without having to run again the whole simulation.

Thanks a lot.
