You can migrate directly to 11.5 and to the new HW with PCD, assuming you meet the requirements for PCD.

Otherwise, DRS backup, DRS restore on new HW and then upgrade.

For the upgrade, mandatory reading is:

A) Upgrade guide

B) Release notes

C) README from ISO

all the requirements, procedure, etc. for the upgrade, are in the above docs.
