Hopefully just a quick question but can I use a newer version of the converter to convert a server to a ESXI 5.5.3 server? Server is 2008R2 and if I try an download the 5.5 converter it brings me to a page that I can only download 6.0 or newer. Thanks in advance
Yes, it will work but if you experience an SSL problems because of TLS 1.0 disablement, you need to change the tag <sslOptions> from 123422720 to 56313856 in converter-server.xml, converter-worker.xml and converter-agent.xml, then restart services, and in converter-client.xml placed in installation folder, then restart the UI.
Depending on the selected source, you can convert it to the following destinations.
Attached in an Excel with what version is supported with what ESXi and vCenter.
