Rotherham plan to upgrade their scouting operation after the departure of head of recruitment Gee Evans.
New manager Alan Stubbs had initially worked closely with Evans - brother of former manager Steve - when he took the hot-seat on June 2.
But it was announced last week that Evans had left the Millers, ending a four-year association.
Stubbs said: “When you come to a club, you make decisions in the best interests of the football club.
“I think we are looking to restructure that side of the club. We will make the necessary appointments to make the club stronger.”
A number of trialists had trained with Rotherham in pre-season but none were offered contracts.
The Millers drew 2-2 with Wolves in Stubbs’ first match in charge on Saturday, with striker Danny Ward scoring with a good header and midfielder Will Vaulks smashing in a stunning long-range volley.
“The first goal was great movement by Wardy. He has looked really sharp all pre-season and in training,” Stubbs said. “Obviously, Will has got that in his armoury. He has scored a few goals before (for Falkirk in Scotland). Hopefully we will see a few more of them.”
Vaulks, aged 22, was man of the match on his debut for Championship Rotherham, having spent the previous two seasons in the Scottish Championship.
“It is a step up,” he said. “I have played in a few big games against Rangers and Hibs - they are probably up there - but it is a lot more physical, faster. Hopefully I will adapt quickly and get used to it.”
The warmth of the Rotherham welcome Vaulks has received has made up for the disruption to his personal life as he adjusts to a new challenge south of the border.
“The manager and his staff are enthusiastic and make you feel welcome and the boys have been brilliant,” he said.
“I am just fed up of being in a hotel, but I hope to get that sorted soon. I have really enjoyed it so far.”
