Was there ever a time that the crew of the Enterprise-E would have worn TNG S1-7 / DS9 / Generations-style uniforms?

Question

In 'First Contact', La Forge makes reference to the crew of the Enterprise-E having been in space for over a year by that point. Given that the revised ST:FC Starfleet uniforms (grey shoulders) were introduced in 'First Contact', and we have an opportunity to observe Starfleet uniform protocol in the year preceding 'First Contact' (by watching 'DS9' and noting when the uniforms change), is it reasonable to assume that Picard and co. spent some time on board the E, rocking the uniforms from the TNG TV era?

*** EDIT ****

I was correctly reminded that in 'Generations' we saw a gradual shift from the 'TNG' TV-era uniforms to the 'DS9'-style uniforms.

However, my question is now: "is it reasonable to assume that Picard and co. spent some time on board the E, rocking the uniforms from the 'Generations'/'DS9' era?"

Answer 1

Yes

In Star Trek Generations, we see the uniform has changed from the TNG TV Era (image 1) to a uniform more resembling the uniforms worn at first on DS9 (image 2)

Starfleet uniforms from the TNG TV Era changed four times:

1. Starfleet uniform Type A (2353-2367/2370) (TNG TV Era)

2. Starfleet uniform Type B (2366 - end of the decade) (TNG TV Era)

3. Starfleet uniform (late 2360s-2372) (Generations)

4. Starfleet uniform (2370s) (First Contact onwards)

Now, the Enterprise-E was launched in 2372, stardate 49827.5 with Picard assuming control shortly thereafter (Source). According to Memory Alpha, the Starfleet Uniform was modified to the last of the three (i.e. the 'grey' uniforms) in 2373. As the Enterprise-E was launched a year prior to that re-design, yes, the crew of the Enterprise-E would have spent some time 'rocking' in the Generations-style uniform for about a year.
