My plan is to upgrade R610 - BIOS 6.6.0, iDrac 2.9.2, ( LifeCycle controller firmware 1.2.0.57 - which does not work when booting BIOS ), OS= MS Hyper-V 10.0.17763.2183 on SSD in the DVD bay. 6x HDD in 3 different raid arrays 1. shutdown 2. swap out Perc 6i with H700 - reuse same battery. 3. reboot, go into Raid setup 4. Import foreign configurations 5. Reboot and enjoy I have read of : a) issues H700 battery condition, and needing to be re initialised, using OMSA    I have downloaded OMSA WINX64 9.3.0-3465_A00.exe    Question - is it safe to install this ? - as i expect to get part way through installing have a crash and not be able to       reboot   b) issues with H700 showing HDDs as offline and not being able to import Foreign configs. c) talk of Drivers - but all videos i've watched, simply swap out the cards, import configs and go. ?   so are drivers required ? Dell support has only Firmware updates. d) tried to download PERCCLI but seems all configs I try - its not available      (Dont know if I will/would need this, but its title seems as if I should have it ?? ) e) once up and running, try the H700 update ( if needed ) 12.10.7-0001 Am I getting a panic attack, or should it simply work, and forget about  a throu' d. I don't want to trash the machine, as it does intimidate me.
My plan Perc i6 to H700 on R610
