Hello GMSS,   I would always recommend to have a backup and that the system is up to date on firmware.   You can move virtual disk from older PERC to newer using Virtual Disk migration   Example: R620 with H710 to R630 with H730 will import your RAID60   Reference :Virtual Disk Migration page 41 [URL]  
Hi, I'm running VMware ESXi 6.5 on my R620 (RAID 60) but unfortunately I'm unable to upgrade to ESXi 7.0 as the R620 is not compatible.  I''ve got an R630 and am looking to swap the disk from my current R620 into my R630 and than perform the upgrade to ESXi 7.0. Will this be possible? Will a straight swap of the disks work and if so, what will I need to be aware of? Many Thanks in advance GMSS
