How to optimize space in Anaplan by unifying versions without affecting the production model?

Hello everybody!
We are working on optimizing a model in Anaplan with the goal of freeing up more space. For this, we are evaluating the possibility of eliminating some versions that are not in use and unifying them into more functional versions. Currently, the model includes many versions, such as FPC 2022 - I and FPC 2022 - II, among others, because each year has multiple versions. We now seek to reduce this to only four versions, linking them to the corresponding years.
However, we are concerned that these changes may affect the production environment, as it contains critical information. Therefore, we are looking for recommendations on how to execute this optimization efficiently and safely, minimizing the risk to the production model.
Also, if anyone has implemented a similar solution or knows of other ways to free up space without deleting versions, we would be very grateful for your help.

This is an example of all the versions we have:

And we want to achieve something like that: that there are only 3 or 4 versions that relate to each year
