For AIPS users who are learning CASA, it is intuitive to think about equivalent tasks between the two software packages. Below are some AIPS-to-CASA equivalent tasks; note that there is not always a one-to-one transformation between the two packages.

| CALIB | gaincal | Calibrate gains (amplitudes and phases) |
| CLCAL | applycal | Apply calibration to data |
| COMB | immath | Combine images |
| CPASS | cpass | Calibrate bandpasses by polynomial fitting |
| DBCON | concat | Concatenate uv datasets |
| DEFAULT | default | Load a task with default parameters |
| FILLM | importvla | Import old-format VLA data |
