HP smart array controller upgrade p800 to p822 and array migration

Hello,

I have a 5/6 years old server HP Proliant DL 360G5 with an HP Smart Array P800/512 controller connected to two MSA60 enclosures: one with 12 2TB SAS HDD and the other with 12 500GB SATA HDD as main file server. (I also have HP StorageWorks 1/8 G2 Tape Autoloader on the same controller)

I no longer want to maintain the DL360, I plan to purchase a new HP Proliant DL380 G8 with a new controller like the P822/2GB for replacement of the DL360.

My questions are:
1) Is the P822 compatible with my old MSA60 ?
2) Can I add new enclosure like HP D2600 on the same P822 as for MSA60 (on another port) ?
3) Can I move my Array to the new controller without having to backup, recreate array on new controller and restore ? ( I know this was possible in the past between different model of hp smart array conroller, but I have not found recent information for P822)
4) Can i connect  HP StorageWorks 1/8 G2 Tape Autoloader to the P822 ?

Best regards

No specific mention of the MSA60/70 but quickspec says "NOTE: The components of a storage subsystem (e.g. the drive, the HBA/controller, firmware, and the server backplane) should operate at the same data transfer rate or the system bandwidth will be negotiated down to an acceptable level for all components." so it should negotiate down to 3Gb/s OK. Understandably HP don't test or certify old kit with new as they want you to spend more cash.

Qickspecs say "Data Compatibility among all models of Smart Array controllers allows simple and easy upgrades any time needs for higher performance, capacity, and availability increase. Even successive generations of Smart Array controllers understand the data format of other Smart Array Controllers." so that's still there, Previous generations won't understand the advanced features of the latest controllers of course but it's never been a guarantee you can downgrade to previous ones, only upgrade to future ones.

The 1/8 G2 is listed in the quickspecs.

Another option would be to simply move the P800 to the new server plus add a P822 for the newer enclosures, You couldn't combine arrays between the two controllers but it does take two full length PCIe cards if you add a 2nd CPU and PCIe riser.
