Hiya
I am trying to work out the difference between these two aviva workplace funds and struggling.

AVIVA MULTI ASSET GROWTH

both asset class breakdowns are exactly same and both perform similar. 
Just curious to why 2 different funds and what am I missing on it.

I have my own SIPP where I am using lifestrategy vanguard 60 along with some other funds and would like to create a similar set up with the very limited choices I have with Aviva...  so really I am looking at why these 2 funds differ and are they in any way similar in holdings to vanguard 60 (or as near to it as I can get).

My aviva pension is currently in my future growth, stewardship managed and blackrock ex uk index tracker but I have a large amount of cash within it after a recent transfer in from a work bonus hence looking at these two lower risk funds
