AOA (80/20) vs ITDC vs AOR (60/40) ... and both AOA and AOR are 20-30 times bigger funds than ITDC ... and no gliding paths

How much money are we talking about? IF we're talking 10k then it's pretty easy to just sell the TDF and buy a single fund like VT or AOA or something.

I would do either VT or AOA. AOA is for if you want a little bond exposure that automatically rebalances without any capital gains issues. It is 80% global equities and 20% bonds, rebalanced regularly inside the tax-efficient ETF wrapper. It is not painful in a taxable account IMO -- currently yielding a little over 2%. But 100% equity with VT is also perfectly reasonable in this situation IMO.

With only 6 years until retirement I’d probably consider something like AOR, maybe AOA if you’re already in good shape and this is just “extra”.

A TOA just moves assets over to the new custodian; assets are only sold when the target custodian cannot manage them. A good example are Fidelity ZERO funds: those are sold and cash is transferred.
Once the TOA is complete, it's your responsibility to sell the asset and buy what you want.
>Is there anything else I need to do with this transfer?
TOA's can take some time to fully complete. Actual assets will transfer quickly, then cash comes later (not too much later, but still delayed), and finally any interest accrued to the account at month-end is transferred. Be patient and don't be surprised if more money appears.
>I don’t mind it being a Hennessy fund held by Vanguard
Holy lord, that expense ratio: [HEIFX – Hennessy Equity and Income Investor Fund Stock Price | Morningstar](https://www.morningstar.com/funds/XNAS/HEIFX/quote). Consider using much cheaper allocation fund of some sort; iShare ETF's are a really good option:

* [iShares Core 60/40 Balanced Allocation ETF | AOR](https://www.ishares.com/us/products/239756/ishares-growth-allocation-etf)
* [iShares Core 40/60 Moderate Allocation ETF | AOM](https://www.ishares.com/us/products/239765/ishares-moderate-allocation-etf)
* [iShares Core 30/70 Conservative Allocation ETF | AOK](https://www.ishares.com/us/products/239733/ishares-conservative-allocation-etf)

The answer is that terms like aggressive/balanced/conservative are industry buzzwords with commonly accepted definitions. An example what I'm talking about is the iShares Allocation funds AOA, AOR, AOM, AOK.
By these definitions, a portfolio of 100% stocks and 0% bonds is considered "most aggressive" no matter how you slice it.
