I would think that it is not. But on a second thought would beleive that making it to be compatible is feasible.
OAS 4.0.8.2 max 8.1.6
iAS starts with 8.1.7
I would suggest that you look into migration OAS to iAS, if you are planning to move on to 8i Rel 3.
I was able to configure the iAS on 8.1.6, 8.1.7. The way the iAS creates those files are differnt from that of OAS in some regards. There are documentations that talks about the compatibility issues in the metalink.
