Microsoft Dynamics (Axapta) aggiornamento

Question

Vorrei aggiornare Axapta dalla versione 2.5 alla 3.0 o 4.0 (da considerare). Probabilmente non sarebbe stato così difficile, ma la mia versione ha un sacco di codice personalizzato - nuove classi, fonti di dati, moduli, ecc e non ho idea di quanto tempo si può prendere. Avete qualche esperienza con l'aggiornamento 2,5-3,0 o 4,0? Quanto difficile può essere di spostare o riscrivere tutte le modifiche insieme con la nuova versione Axapta? Sarò grato per qualsiasi tipo di aiuto.

Answer 1

Fist off, I wonder why you consider to upgrade to Axapta 3.0 (from Oct 2002) or Axapta 4.0 (Mar 2006), when there is newer alternatives like AX 2012 available right now.

Element types

Generally new elements (forms, classes etc.) poses only minor problems when upgrading. Modified elements are much more time consuming. Data structure changes may also pose challenges as it may require rewrites. Reports may be very time consuming to upgrade. A total rewrite of an element should always be considered, it is sometimes faster.

Compare process

The upgrade process for an individual modified element is usually straightforward when you use the compare tool (twice). Compare your old layer with old original layer, and compare new layer with new original layer. The modifications should match more or less.

Estimation report

AX 2009 provides an estimation report located in Tools\Development tools\Code upgrade\Estimation report. The time estimate is based on an estimated average time to upgrade certain code conflicts (setup in the parameters).

I have no prior experience with the report, but the any estimate is uncertain with 50% at least.
