The farewell was attended by Chief Minister Lal Thanhawla, two of his cabinet colleagues and top officials.
Raj Bhavan sources here said he would first go to Chennai for medical check-up and then go to his home state Kerala.
The farewell had to be organised in a hurry as the governor's visit to Chennai was planned earlier, before his new appointment to Nagaland with additional charge of Tripura was announced, protocol department officials said.
They said because of lack of time it could not be held at the Raj Bhavan where Purushothaman was sworn-in as the Mizoram Governor on September 2, 2011.
The new Governor Dr Kamla Beniwal would be sworn-in at the Raj Bhavan here at this evening.
