Upgrade from EXTJS 4 to EXTJS 6

Ever thought of upgrading your application in EXTJS 4 to EXTJS 6.
I just did. And no wonder, there were plethora of issues. 

What I did for my convenience was to list them down. I have placed the table below.
Hope it helps you as well.

Do leave me a comment, if the post helps you!!

Purpose	Before	Now
Header config	proxy.proxyConfig.headers	proxy.config.headers
Proxy config	proxy.reader.root	proxy.reader.rootProperty
	doComponentLayout()	updateLayout()
Fetch the operation	request.operation	request._operation
Fetch the records	operation.records	operation._records
Fetch column data	record.raw.Values	record.data.Values
Locale file names	ext-'locale'.js	locale-'locale'.js
Combo box select	record[0].data.value	combo.getValue()
Renderer listener	_meta.tdAttr	meta.style

I do plan to add some more issues that I came across. Those shall be a part of subsequent posts.
