Registration Statement on Form S-8
Ladies and Gentlemen:
We refer to the Registration Statement on Form S-8 (the “Registration Statement”) being filed by Allscripts-Misys Healthcare Solutions, Inc., a Delaware corporation (the “Company”), with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), relating to the registration of 10,000,000 shares (the “Registered Shares”) of common stock, par value $0.01 per share, of the Company (“Common Stock”), to be issued pursuant to the Company’s Amended and Restated 1993 Stock Incentive Plan, as amended (the “Plan”).
We are familiar with the Plan, the Registration Statement, the Second Amended and Restated Certificate of Incorporation of the Company, the Bylaws of the Company and the resolutions of the Board of Directors of the Company relating to the Plan and the Registration Statement. We have also examined such records, documents and questions of law, and have satisfied ourselves as to such matters of fact, as we have considered relevant and necessary as a basis for the opinions set forth herein. We have assumed the authenticity of all documents submitted to us as originals, the genuineness of all signatures, the legal capacity of all natural persons and the conformity with the original documents of any copies thereof submitted to us for our examination.
Based on the foregoing, and subject to the qualifications and limitations hereinafter set forth, we are of the opinion that:
| 1. | The Company is a corporation validly existing under the laws of the State of Delaware. |
| 2. | Each Registered Share that is newly issued under the Plan will be legally issued, fully paid and non-assessable when (i) the stockholders of the Company shall have approved an amendment to the Plan to increase the number of shares of Common Stock that may be issued pursuant to the Plan by 10,000,000; (ii) the shareholders of Misys plc, which |

This opinion letter is limited to the General Corporation Law of the State of Delaware.
We do not find it necessary for the purposes of this opinion letter to cover, and accordingly we express no opinion as to, the application of the securities or blue sky laws of the various states or the District of Columbia to the issuance or sale of the Registered Shares.
We hereby consent to the filing of this opinion letter as Exhibit 5.1 to the Registration Statement and to all references to our firm included in or made a part of the Registration Statement. In giving such consent, we do not thereby admit that we are within the category of persons for whom consent is required by Section 7 of the Securities Act or the related rules promulgated by the Commission thereunder.

Very truly yours, |
