 Transferring an entire maxi ISA to the maxi ISA of another ISA manager. Transferring a mini ISA from last year to a mini ISA for this year. Transferring a maxi ISA from two years ago to a maxi ISA for this year. Transferring a maxi ISA to a mini ISA for another ISA manager. Putting extra money into either a mini or maxi ISA.
