Do I have too much MSFT exposure? 100% MSFT stock with $80k+ gains AND invested in XLK and SCHG ETFs

I have $80k in gains for MSFT stock in one account so 100% of the portfolio there, and also hold funds like XLK and SCHG in another account which I am slowly DCA'ing into and building. Part of me wants to keep my MSFT shares in the first account (I used to work there so it came with the ESPP) since the gains are enormous, and I sold a bunch over the years (1,000 shares) due to too much concentration and now with this massive gain + owning XLK and SCHG I feel like I am overly concentrated in MSFT. Of course if I never sold 1,000 shares I'd be up like $500k but it's risky. Thinking of slowly selling my MSFT shares over the next 6-12 months to better diversify and put that $ into the 2 ETFs XLK and SCHG since I already have MSFT exposure there? XLK has 22% MSFT holdings and SCHG has 12% MSFT holdings… definitely better for diversification. Thoughts?
