Dependen (spouse) status after T1 Entr (main App) got ILR ??

I need to ask about the status of my wife please.
She came to UK in May 2014 as my dependent. I was on T1 entrepreneur visa that time and got ILR last month June 2015 on that base. Dependent visa of my is valid till Feb 2017. Does She has to switch her visa to some other category because I have got ILR OR she can continue with same visa till FEB 2007.
Please advise.
Someone told us that she has to reapply for visa within 2 months otherwise her status will be illegal in UK. It seems very unlikely .

Thanks

If you got ILR based on 5 years residence as a Tier 1 E migrant, your wife can stay on her current Tier 1 E Dep visa and extend it is in 2017 for a further 2 years to meet the requirements before she can apply for ILR.

She does not need to change visa category. This is only applicable to dependents of migrants who apply for ILR based on 10 years long residence.
