Hi there and a warm welcome from a semi-ex OBOD-ie.
Many OBOD members are also, or have been, Wiccan. Both new 'religions' were born and developed in the mid-20th century from the same background sources: Freemasonry /the Golden Dawn / Theosophy / Rosicrucianism ... loosely speaking, different interpretations & presentations of a basically neo-Gnostic understanding. So it won't be a fundamental change for you.

Some forms of practice are more formally organised than others; eg some forms of Wicca have lots more rules & regulations and rigid initiations than Druidry, which contains a far more varied & ever-changing variety of homespun ceremonies, rituals, Grove meetings etc.
I used to know the 'Chosen Chief' / re-creator of modern neo-druidry & his family when I was a member, from many Order meetings, Glastonbury Assemblies & Eisteddfods, workshops, week-long Lughnasadh camps etc & he gave many talks about it all. It has changed & developed and grown hugely since I joined in 1999, and the course has changed too.
Sending you many good wishes & bright blessings on this new turn in your journey!

ps I suppose you know that Philip & Stephanie Carr-Gomm & co were / are Wiccan too - hence calling their tarot deck the "DruidCraft"!
