Minimum spacing between an existing anchor and new anchor

In one of our UCW Project in KSA, we need to replace the alum floor bracket and Hilti expansion anchor installed on site with a new bracket and anchors, the load conditions are not changing. We will chop off the head of the existing anchor and drill a new hole for the new anchors. What is the minimum spacing required between the chopped of anchor and new anchor that we are going to install as per Hilti requirement? We are planning to place the new anchor 50 mm (2.0") away from the existing anchors. Is it ok? Please refer to the attached image for more details.
