Would appreciate all types of advise on repotting my green island fig

Having issues uploading a pic of my bonsai, but within the last six monthsI have brought this tree back in full from the clutches of death.
The tree now has out grown it original pot. And I now wish to re-pot to encourage more growth. I would greatly appreciate any and all types advice on when and how best to accomplish this task especially root management and care.
I truly am starting to fall in love with this tree and want to provide the best care for it in the future. Please help.
Thank you.

We need to see a photo of the tree to be able to offer specific advice. It would seem very unlikely that if it nearly died 6 months ago it would need potting on already. GI figs are very slow growers. Depending on the size of the tree will determine whether you up pot it or just prune the roots and rut it back in the same pot.
