Upgrading server question

[Svelmold]

I have an odd setup I think that I am looking into upgrading. I use an old dell poweredge server with a perc h700 raid controller for the 8 hot swappable drives on the front. I have them set up as individual raid arrays so that unraid can control what files end up on each drive and not the raid controller. I am upgrading all of the hardware to a newer poweredge server I was going to set it up with a similar type of setup letting unraid handle the drives again, my question is if I just transfer the drives over to the new server which has a newer raid controller card will unriad still be able to know that the drives I transfer over were the same drives as before? Obviously I am trying to not have to do massive file transfers and just use the same drives until I go through more effort to upgrade them to larger drives. I don't want to take the chance that it might cause data loss when I transfer over. has anyone experienced anything like this or have any suggestions to try without risking data loss? As far as I am concerned if the answer is no don't try you are better off setting it up to transfer files for a week I will transfer files for a week but I thought I would reach out to the community and ask 

 

if it helps at all in the Identification: fields on all of the drives look similar to this

PERC_H700_00e2177105e3ae692300961f34b0bc82_36782bcb0341f96002369aee3057117e2

 

its the fact that it says PERC_H700 in the beginning of the identification that makes me question if unraid will be able to match up the drives.

 

thanks in advance for anyone who has any info

Most likely not, and in that case you could do a new config but there's a not so small change that the disks won't mount, it's usually possible to fix but it involves rebuilding all the disks one at the time, like this:

Thanks for the reply. In my case I am actually migrating 2 old unraid servers into 1 new one and was going to be buying new hard drives anyway, so the slow method of transferring files is a real option for me. Without a clear "of course you can" I think I am going to go with the safer slower method.
