Will changes made to Budget Pool impact the previous cycles' data

Summary:

Will changing the Budget Pool Grouping from 'Company' to 'Legal Employer' impact the previous cycles.

Content (required):

We are moving from a four business unit model to a single business unit and in the process of doing impact analysis.

We currently having budget pools grouped by Company and are looking to change this to group by Legal Employer as we would be having only one business unit going forward. Will this change in configuration of the Budget Pool grouping have any impact on the previous cycles (where in we grouped by Company)?

Thank you!
