Scotland defence coach Matt Taylor says incoming boss Gregor Townsend should follow the blueprint of predecessor Vern Cotter.
Glasgow coach Townsend takes over from the Kiwi next summer after the SRU confirmed Cotter's contract would not be renewed at the conclusion of the 2017 Six Nations.
Taylor works closely with both men - assisting Townsend at Glasgow while also helping Cotter prepare the Dark Blues - and believes the latter has put Scotland on the path to success
"I'm lucky enough that I'm in the Scotland set-up under Vern but also work with Gregor at Glasgow," said Australian-born Taylor who will remain Townsend's No 2 with the national side.
"There hasn't been a formal plan drawn up [to ensure a smooth transition] but I know Gregor is on the phone to Vern a lot and they talk about different things.
"I report back to Gregor too and tell him what we're doing here in the Scotland camp and how we're doing it. He recently said to me to make a note of anything that works well so we can continue with it going forward.
"Gregor is very detailed in his coaching so he is very conscious of things that work well and things that can be improved on. I would imagine he is only thinking about making small adaptations rather than wholesale changes.
"He will want to put his own spin on things as all new coaches do but he'd be crazy to change everything, because we're doing reasonably well. So there will be things that change, but also things that stay the same."
Townsend could be left with a nasty hangover of the Cotter era, however, should Scotland lose out to Argentina on Saturday.
Scotland - ranked ninth in the world, one place behind the Pumas - can overtake them with a win at Murrayfield. Defeat, however, could have a knock-on effect for their World Cup seeding hopes.
The draw for Japan 2019 takes place next May and governing body World Rugby will use the rankings to calculate the seeding for the pool stage.
If Scotland end up outside the top eight, they face the daunting prospect of having to overcome two major nations to make the quarter-finals.
But Taylor said: "We have talked about winning and the processes we need to win, but we haven't said we need to win because of our ranking. We know in the back of our minds it's important but so is winning every Test match.
"You're right to say this game has more importance in that sense but does that add pressure by saying that to the players? We're not preparing any less but of course we understand it. We're just looking to win first and foremost."
