When installing an enhancing belief is it necessary to get get rid of a
limiting belief first. I.e. Is it necessary use Session A to elliminate a negative belief to be replaced with and enhancing belief using session B.
No, it does not matter, you can plant positive beliefs without weeding out negative beliefs. Weeding out the negatives just helps to prepare the soil.
Sometimes my mind got into a weeding out the negative mode and for a couple sessions all I could think of was negatives to eliminate. Another time I would get stuck in planting positives. Sometimes a mode is nice because you get a chance to get to the real essence of what you are trying to achieve.
It's difficult to identify a limiting beliefs in the first place so weeding them out can be difficult. It's easier to plant new beliefs and keep nourishing them. Since some of those limiting beliefs may still be necessary to keep harmony with you values. It's wise to check that beliefs you want to adopt are also in harmony.
