Proper VLAN removal

Greetings,

I am working in an environment that has an HP 5412zl Chassis (core) with Multiple HP 3500yl switches in other closets that connect back to the core.  Currently, there is a VLAN created for wireless access points, and one for phones.  The on-site contact thought they were created for bandwidth management, but wasn't sure.  
I recently installed new Meraki wireless access points to replace some HP LWAP's , and some of them are going into new switch ports (they didn't previously have an access point plugged into them.)  The access points plugged into the new ports, aren't connecting to the Internet and/or the wireless cloud controller, presumably because of the VLAN configuration.  I really don't even need the VLAN's anymore, as the guest traffic with the Meraki solution is doesn't require it.  Does anyone see any issue with simply removing the VLAN's? (See attached photo)

Will the port taggings for the wireless VLAN just default back to the main default VLAN if it is just removed?

Thanks in advance

I would set the existing untagged ports for for the old VLAN to untagged for your default VLAN, and see if you are then able to access to the internet from your new APs. After you have verified all is working then remove the old VLAN. Also take a config backup before you do it, just in case!

I used THIS DOCUMENT to help myself with ProCurve hardware ("HP ProCurve Switch Software Advanced Traffic Management Guide").
Particularly interesting part for you (Page2-16):
Deleting Static VLANs: On the switches covered in this guide you can delete a VLAN regardless of whether there are currently any ports belonging to that VLAN. (The ports are moved to the default VLAN.)
As for VLANs themselves... How would you like to separate i.e. guest WiFi from production network?
