Matthew Tipton has been appointed as Portadown manager on a two and a half year contract.
Tipton takes charge of the Irish Championship club after stepping down as Warrenpoint Town boss.
The former Portadown striker returns to Shamrock Park to succeed Niall Currie, who was sacked on Saturday.
Ports are fifth in the Championship table and are seven points off a play-off spot after one win from their last five league matches.
Tipton's first game in charge is against second place Newry City on Friday, 2 March.
Currie was dismissed following a scoreless draw with HW Welders, which left the club 15 points behind leaders Institute in the table.
A statement by the club confirmed the appointment of the Welshman up to the end of the 2019/20 season.
Former goalkeeper David Miskelly has agreed to return to Portadown as Tipton's assistant manager while Chris Wright will join Trevor Williamson as the club's first team coaches.
Portadown asked Warrenpoint for permission to speak to Tipton on Monday and Town officials gave the go-ahead for the Welshman to hold talks with his former club.
"You get opportunities and you grab them," said Tipton.
"This was an opportunity at the right time for me.
"I didn't want to see somebody else coming here. I wanted to be the one to bring the club back to where I believe it should be."
Tipton succeeded Barry Gray as Warrenpoint manager three months into the 2016-17 campaign but went on to guide the club to promotion to the Premiership in his first season in charge.
Warrenpoint have gained many admirers for their attacking style of football this season but they have earned only two wins in their last 14 Premiership games and are now four points ahead of Carrick Rangers who occupy the relegation play-off spot.
A Warrenpoint Town statement said the club had "parted ways by mutual consent following a conversation" after Tuesday's 5-0 defeat by Glentoran.
Former Warrenpoint player Stephen McDonnell will take over as interim manager under the end of the season.
