Doubts about upgrading to openlab 2.7/2.6 from Openlab 2.3

Hello,

We currently work with OpenLAB CDS 2.3 and are thinking of upgrading the software to 2.6 / 2.7.
The following doubts have arisen:

- Will it be necessary to create the acquisition methods again?
- Will it be necessary to create the processing methods again?
- Will it be necessary to create the Intelligent Reports again?
- What will be the most significant changes at the user level that we will find in the update?

Thank you very much!!
