My company is going to be migrating from on prem to an all SaaS world. We currently have a DC that will be going away in the next year and about a 1/4 of our locations will be moving off MPLS to DIA circuits with Meraki equipment. For the sites that will remain at MPLS after the DC goes away my question is how do I get these sites to get to our internal network, I am thinking that SDWAN is an option but I am not familiar enough with it. I am looking for other possible solutions for this as well. I have already had the conversation about why the DC needs to stay in place until we get all sites migrated but have gone on deaf ears.
Thanks.
