We present a detailed analysis of a cool-core galaxy cluster Abell 3017, at aredshift of z=0.219, which has been identified to be merging with its companioncluster Abell 3016. This study has made use of X-ray Chandra, UV (GALEX),optical (ESO/VLT), mid-infrared (WISE), and radio uGMRT observations of thiscluster. Using various image processing techniques, such as unsharp masking,2-d fits using Beta models, contour binning and the use of surface brightnessprofiles, we show the existence of a pair of X-ray cavities, at a projecteddistance of $\sim$20'' (70 kpc) and $\sim$16'' (57 kpc), respectively from thecore of Abell~3017. We also detect an excess of X-ray emission located at 25''$\sim$(88 kpc) south of the centre of Abell 3017, is likely due to the bulkmotions in the ICM either by gas sloshing or ram-pressure striping due to amerger. We find that the radio lobes are responsible for the observed X-raycavities detected in this system. The lower values of the mid-IR WISE colour[W1-W2] and [W2-W3] imply that the central BCG of Abell~3017 is a star-forminggalaxy. The current star formation rate of the central BCG, estimated from the${\rm H\alpha}$ and GALEX FUV luminosities, are equal to be $\sim 5.06\pm 0.78$Msun yr$^{-1}$ and $\sim 9.20\pm 0.81$ Msun yr$^{-1}$, respectively. We detect,for the first time, a radio phoenix $\sim$150 kpc away from the radio core,with a spectral index of ($\alpha \!\leq\! -1.8$). We also report the detectionof $\rm~Pa_\alpha$ emission in this cluster using ESO VLT SINFONI imaging data.
