Selling OEIC Funds with existing provider to buy ETFs and transfer to Freetrade

I currently hold a number of OEIC funds in both my ISA and SIPP and looking at ways to save fees and earn cashback on the move. I know Freetrade doesn’t offer OEIC’s only ETF’s, so I thought it would be the ideal time to convert my existing holdings with my current provider over to ETF’s.

I currently hold the following OEIC’s (I’ve built them up over years). The fund with the most invested is the Vanguard LifeStrategy (Around 40% of my portfolio), so it is going to take many trades to sell these off (at a cost too) with my existing provider (Interactive Investor).

I’m thinking of going for low cost tracker ETF’s of some type (I’m still researching). The bulk I’m expecting to place into one of these.

VWRP - Vanguard FTSE All-World UCITS ETF (0.22% TER)
HMWO - HSBC MSCI World UCTIS (0.15% TER)
WEBG - Amundi Prime All country World UCITS ETF (0.07% TER)
LGGG - L&G Global Equity UCITS ETF (0.10% TER)

All the above seem extremely similar ETF’s, with the main differences being fees and the number of holdings contained within each, with the Vanguard being the highest with over 3,600.

What are people’s thoughts on this - I’d love to hear what people have to say about my planned ETF’s, current portfolio, etc.

Thanks in advance
