If you are contemplating using a new payment gateway, new CRM or ERP integration, a major re-design or a significant customisation, it may make sense to develop these on Magento 2 and include them as part of your migration process rather than developing these on Magento 1 and then having to redevelop such customisations all over again on Magento 2.
Kama wewe ni kutafakari kwa kutumia malipo mpya gateway, ali mpya au ERP ushirikiano, kubwa re-kubuni au customization muhimu, inaweza kuleta hisia ya kuendeleza haya juu ya Magento 2 na pamoja nao kama sehemu ya mchakato yako uhamiaji badala ya kuendeleza haya juu ya Magento 1 na kisha kuwa redevelop customisations kama tena juu ya Magento 2.
