Subject IBO 4.9.x on Delphi XE 4

Hi everybody!

We're migrating our app from Delphi XE to XE4. 

At this moment, we're using IBO 4.9.12, because in the past we found some impediments to migrate to IBO 5. Our app is huge and some IBO5's   requirements are painfull to us.

I'd like to know if it's possible to use IBO 4.9.x on Delphi XE4.

Thanks so much.
