what is best practice to migrate the backup data from old library to new library we have an old hp library , as part of the hardware refresh we introduced new library exagrid , we are using software deduplication , but the exagrid team recommending on having fresh backup , not to migrate the data from old library as it might affect the hardware deduplication. what is the diffrence between moving the mount path , and creating new stroage pool , creating aux copy and promoting it to primary once the it sync , which option is better if we have like 30tb baseline size ? when we do the aux copy , the secondary copy has any affect on the priamry libarary storage , or deduplication ?
