  Once there is a decision of rebalancing or updating a portfolio of funds, the
process of changing the current portfolio to the target one, involves a set of
transactions that are susceptible of being optimized. This is particularly
relevant when managers have to handle the implications of different types of
instruments. In this work we present linear programming and heuristic search
approaches that produce plans for executing the update. The evaluation of our
proposals shows cost improvements over the compared based strategy. The models
can be easily extended to other realistic scenarios in which a holistic
portfolio management is required
