Yes, overall looks good to me, I reviewed EightToSevenDowngradeHandler in detail and it should be good, the other changes are minor besides that meta client refresh change.

@bvaradar Have not looked very closely. but can we also make sure the lsm timeline moves along with new folder.. Call it history instead of archived?

so

.hoodie 
   |______timeline <-- active lives here
                       |________ history <-- lsm lives here.

over 1.1 or 1.2 I want to fully converge it to a single timeline.
