Paul Hamerman, an analyst with Forrester Research, said he expects Hyperion users to fare well because "Oracle wants to keep these customers renewing their maintenance contracts."

"The products themselves and the customers' ability to get support and enhancements on those products is not going to be jeopardized at all," he said.

However, he noted that Oracle typically increases maintenance costs for users over time, which could be a concern to some Hyperion users.

"The challenge will be to integrate Hyperion products as the leading products and integrate them with the ERP transactional system," Hamerman said.
